Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Children born to mothers 18 years and older while pregnant
  • Parents speak English and/or Spanish
  • At least one caregiver in the home must have at least an 8th-grade education level
  • Children still being breastfed into toddlerhood will be eligible to participate. Breastfeeding frequency and duration will be tracked in this case for statistical model adjustment.

Exclusion criteria

Exclusion Criteria:

  • Children regularly taking probiotics and/or antibiotics (e.g., due to chronic ear infections)
  • Children with known allergies to cow's milk or oat products
  • Children introduced to fluid cow's or oat milk prior to 12 months of age however, yogurt and cheese made from cow's or oat milk will be acceptable and will be quantified for model adjustment during statistical analyses
  • Children born with growth, chromosomal, or genetic abnormality, developmental and cognitive impairments, or severe comorbidity that could impact growth and development
  • Children born with congenital abnormalities or developmental delays
  • Children born with birth weights \<2500 g or >4000 g
  • Biological mothers must have no known substance use during the child's pregnancy (alcohol, tobacco, marijuana, or illegal drugs)
  • Biological mothers who experienced a high-risk pregnancy (e.g., preeclampsia, diabetes-Types 1 and 2 and gestational, , etc.) that affected child growth
  • A family history of dairy or gluten (oats are sometimes contaminated with gluten) allergies will be evaluated to assess the child's risk. If either the child's mother or father is allergic to dairy and/or gluten, physician clearance for child participation will be needed
  • The toddler's biological parents have heritable diseases that could influence the findings (e.g., autism).

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

What researchers measure

Primary outcomes

  1. Gut Microbiome Diversity

    Microbial DNA extracted from toddler stool samples will undergo shotgun metagenomic sequencing to identify the unique species present in the gut microbial community and evaluate the richness and abundance of microbes present in the stool.

    Time frame: At enrollment to the end of treatment at 12 months

  2. Toddler length

    Toddler length will be assessed with a pediatric length board and reported in centimeters.

    Time frame: From enrollment to the end of treatment at 12 months

  3. Toddler weight

    Infant weight will be assessed with a calibrated scale and reported in grams.

    Time frame: From enrollment to the end of treatment at 12 months

  4. Vineland Adaptive Behavior Scale (Vinland-3)

    A questionnaire completed by the parent/caregiver that is normed for ages from birth through 90 years. The tool assesses adaptive behaviors (things people do to function in everyday life) in three domains: communication, daily living skills, and socialization.

    Time frame: From enrollment to the end of treatment at 12 months

  5. McArthur Bates Communicative Development Inventories III (MBCDI-III)

    A widely used checklist completed by parents to assess children's early communication skills such as comprehension and use of gestures and words.

    Time frame: From enrollment to the end of treatment at 12 months

  6. Mullen Scales of Early Learning

    Study staff will administer a structured 15-minute play session with the infant to objectively assess motor, visual, and early language skills.

    Time frame: From enrollment to the end of treatment at 12 months

  7. Brief Infant Sleep Questionnaire - Extended

    Sleep location, duration, quality, and interactions; validated for infants and toddlers through age 3 years; REDCap online. Scores range from 0-100 with higher scores representing healthier, more consolidated sleep patterns (e.g., shorter time to fall asleep, fewer and shorter night wakings).

    Time frame: From enrollment to the end of treatment at 12 months

  8. Sleep-Wake Patterns measured by actigraphy (time awake and asleep)

    Actigraphy is a standard, valid, noninvasive measure for assessing sleep and circadian rhythm patterns across the life course. For infants and young children (e.g., toddlers), the actigraph is a small watch-like device that will be worn around the left ankle to record body motion (activity counts). The child will wear the devices for 7 continuous days and nights after all in-home visits. Constant assessment is necessary to capture the full development of sleep-wake patterns and circadian rhythmicity across toddlerhood. Home visits will be scheduled to avoid current illnesses or well-visits to avoid vaccination effects on sleep patterns. Primary sleep variables will be averaged across the recording period. Data will be reported in minutes of time that the child is awake or asleep.

    Time frame: From enrollment to the end of treatment at 12 months

  9. Parent-Reported Sleep-Wake Patterns (time awake and asleep, and number of naps and perceived quality of sleep episodes)

    During actigraphy data collection, the parent/guardian will complete sleep diaries on the sleep of their toddler. Diaries will be used to identify artifacts that might affect motion (externally induced motion e.g. car seat, swing, or constricted motion e.g. swaddling), and to define sleep periods from actigraphy outputs for children prior to analysis with the sleep-wake algorithms. Primary sleep diary variables will be (1) bed/nap clock times attempted to sleep, (2) bed/nap clock times of sleep bout awakenings, and (3) time in bed or interval between attempted bed and wake times.

    Time frame: From enrollment to the end of treatment at 12 months

  10. Home Observation for Measurement of the Environment Inventory (quality and extent of stimulation, support, and learning resources in the home)

    Research personnel will objectively evaluate the caring environment in which a child is raised and parent-child interaction using this validated assessment. The inventory qualitatively assesses the quality and extent of stimulation, support, and learning resources available in a child's home environment.

    Time frame: From enrollment to the end of treatment at 12 months

Secondary outcomes

  1. Infant 24-hour Diet Records

    Habitual intake will be assessed via the Automated Self-Administered 24-hr recall software (ASA24) on 2 weekdays and one weekend day developed by the National Cancer Institute.

    Time frame: From enrollment to the end of treatment at 12 months

  2. Food intake photos showing the infant consuming intervention foods (compliance measure)

    Pre-post meal photos of the infant and their food will be provided by the parents. These images will be used to help corroborate dietary intake and behavior data.

    Time frame: From enrollment to the end of treatment at 12 months

  3. Centers for Disease Control Infant Feeding Questionnaire to assess feeding practices in toddlerhood

    This questionnaire asks about breastfeeding, formula feeding, complementary feeding, introduction to solid foods, food allergies, and participation in the Special Supplemental Nutrition Assistance Program for Women, Infant, and Children.

    Time frame: From enrollment to the end of treatment at 12 months

  4. Food Security Screener

    The USDA 6-Item Food Security Screener will be used to assess household food insecurity. Scores range from 0-6 with higher scores representing higher levels of food insecurity.

    Time frame: From enrollment to the end of treatment at 12 months

  5. Comprehensive Early Childhood Allergy Questionnaire

    Will be used to evaluate allergy exposures and risk across the study period. This is a checklist of various common allergies that parents report the child having or not having each allergy.

    Time frame: From enrollment to the end of treatment at 12 months

Other outcomes

  1. Stool Consistency

    Parents will be asked to classify the stool consistency using the picture-based Brussels Infant and Toddler Stool Scale (BITSS), developed specifically for non-toilet-trained children.

    Time frame: From enrollment to the end of treatment at 12 months

  2. Gastrointestinal and Gastroesophageal Reflux (GIGER) Scale for Infants and Toddlers

    To assess children's experiences of gastrointestinal and gastroesophageal reflux symptoms. A total score is calculated as a sum of responses from 36 questions. Higher scores indicate greater symptom burden, and scores range from 0 to 180

    Time frame: From enrollment to the end of treatment at 12 months
