Infant Behavior

In the early stages of life, newborns are dependent on caregivers to meet their basic needs for survival, feeding, and care. Generally, mothers assume primary responsibility for meeting their infants' basic needs and providing care, while fathers take on a supporting role. Both mothers and fathers actively contribute to the baby's healthy emotional development. This study, planned with fathers of 4-6 month old infants, addresses the lack of quantitative evidence regarding the relationship between fathers' involvement in infant care and infants' sensory processing.

The goal of this clinical trial is to learn if the Talk With Me Baby (TWMB) program improves the home-language environment for at-risk families with children ages two to six months when primary care providers deliver the program during well-child checkups. The main question it aims to answer is: Will the TWMB program increase the time a caregiver talks to their infant? Participants will: 1. Come to at least four well-child checkups 2. Receive the TWMB program from the provider during the checkups 3. Record their conversations with their infant before they receive the program and after they receive the program four times.

The goal of this clinical trial is to test the effectiveness of a Smart Bassinet to prevent/mitigate postpartum mood disorders by augmenting maternal sleep and/or enhancing infant sleep. The investigators will conduct a 2-arm randomized controlled trial (RCT) to compare infant and maternal sleep of infants who use a smart bassinet (SB) or a standard commercially available bassinet (Halo Bassinest Swivel Sleeper 3.0) (usual/traditional care (TAU)). After confirmation of eligibility, participants (N = 342) will randomly be assigned to either the SB or TAU. The investigators hypothesize that use of the SB will be associated with better infant and maternal sleep over a 6-month period, and these mothers will report fewer depressive and anxiety symptoms across the postpartum. The main question\[s\] it aims to answer \[is/are\]: Aim 1: Determine the effect of the SB on infant sleep and maternal sleep. \[primary hypothesis or outcome measure 2\]? Aim 2: Determine the effect of the SB on maternal postpartum depressive symptoms and evaluate the model that the association between the SB and postpartum depressive symptoms is mediated by both infant and maternal sleep Aim 3: Compare trajectory of immune system function from late pregnancy through postpartum between PPD and non-PPD and between SB and TAU groups Exploratory Aim. Evaluate whether the elevated risk demonstrated by previously identified PPD epigenetic biomarkers at the TTC9B and HP1BP3 genes can be modified by using a SB. The investigators hypothesize that the elevated risk will be reduced in the SB condition compared to TAU. Military-affiliated pregnant women will be recruited from across the US via social media and advertising. Monthly online questionnaires will be completed by the mother. Objective sleep data will be collected monthly using an actigraph for 1-week from both mother and baby. Blood samples for assay of inflammatory markers will be collected at enrollment, 3- and 6- months postpartum.
