This study sought to determine the relationship between maternal controlling feeding styles and maternal perception of their infant's ability to regulate feeding and infant weight. A cross-sectional survey of 208 mothers with infants between 2 weeks and 6 months old was performed in a private pediatric office. The authors assessed the relationship between restrictive and pressuring feeding styles with (a) maternal perception of the infant's ability to regulate feeding and (b) infant weight (both actual and perceived). Restrictive feeding style was associated with the perception that infants could not recognize their own hunger or satiety and with concern that the infant would become overweight in the future. Pressuring feeding style was associated with the perception that the baby's appetite is less than other babies and with concern that the infant would become underweight in the future. Maternal perceptions of infant feeding and weight should be incorporated into early obesity prevention strategies.

OBJECTIVE: Medication dosing errors by parents are frequent. We sought to whether a pictographic dosing diagram could improve parent ability to dose infant acetaminophen, and to determine whether pictogram benefit varies by health literacy level. METHODS: We conducted an experimental study of parents presenting with their children to an urban public hospital pediatric clinic. Caregivers were randomized to dose infant acetaminophen with a standard dropper using text-only or text-plus-pictogram instructions (pictographic diagram of dose). The primary outcome variable was dosing accuracy (error defined as >20% deviation above/below dose; large overdosing error defined as >1.5 times recommended dose). Caregiver health literacy was assessed by means of the Newest Vital Sign measure. RESULTS: A total of 299 parents were assessed (144 text-only instructions; 155 text plus pictogram); 77.9% had limited health literacy (Newest Vital Sign score 0-3). Text-plus-pictogram recipients were less likely to make an error compared to text-only recipients (43.9% vs 59.0%, P = .01; absolute risk reduction, 15.2% [95% confidence interval, 3.8-26.0]; number needed to treat, 7 [4-26]). Of text-plus-pictogram recipients, 0.6% made a large overdosing error compared to 5.6% of text-only recipients (absolute risk reduction, 4.9% [0.9-10.0]; number needed to treat, 20 [10-108]). Pictogram benefit varied by health literacy, with a statistically significant difference in dosing error evident in the text-plus-pictogram group compared to the text-only group among parents with low health literacy (50.4% vs 66.4%; P = .02), but not for parents with adequate health literacy (P = .7). CONCLUSIONS: Inclusion of pictographic dosing diagrams as part of written medication instructions for infant acetaminophen may help parents provide doses of medication more accurately, especially those with low health literacy. High error rates, even among parents with adequate health literacy, suggest that additional study of strategies to optimize dosing is needed

OBJECTIVE: To determine whether duration and content of media exposure in 6-month-old infants are associated with development at age 14 months. DESIGN: Longitudinal analysis of 259 mother-infant dyads participating in a long-term study related to early child development, from November 23, 2005, through January 14, 2008. SETTING: An urban public hospital. PARTICIPANTS: Mothers with low socioeconomic status and their infants. Main Exposure Duration and content of media exposure at age 6 months. MAIN OUTCOME MEASURES: Cognitive and language development at age 14 months. RESULTS: Of 259 infants, 249 (96.1%) were exposed to media at age 6 months, with mean (SD) total exposure of 152.7 (124.5) min/d. In unadjusted and adjusted analyses, duration of media exposure at age 6 months was associated with lower cognitive development at age 14 months (unadjusted: r = -0.17, P < .01; adjusted: beta = -0.15, P = .02) and lower language development (r = -0.16, P < .01; beta = -0.16, P < .01). Of 3 types of content assessed, only 1 (older child/adult-oriented) was associated with lower cognitive and language development at age 14 months. No significant associations were seen with exposure to young child-oriented educational or noneducational content. CONCLUSIONS: This study is the first, to our knowledge, to have longitudinally assessed associations between media exposure in infancy and subsequent developmental outcomes in children from families with low socioeconomic status in the United States. Findings provide strong evidence in support of the American Academy of Pediatrics recommendations of no media exposure prior to age 2 years, although further research is needed

The goal of this study was to determine whether verbal interactions between mothers and their 6-month-old infants during media exposure ('media verbal interactions') might have direct positive impacts, or mitigate any potential adverse impacts of media exposure, on language development at 14 months. For 253 low-income mother-infant dyads participating in a longitudinal study, media exposure and media verbal interactions were assessed using 24-hour recall diaries. Additionally, general level of cognitive stimulation in the home [StimQ] was assessed at 6 months and language development [Preschool Language Scale-4] was assessed at 14 months. Results suggest that media verbal interactions play a role in the language development of infants from low-income, immigrant families. Evidence showed that media verbal interactions moderated adverse impacts of media exposure found on 14-month language development, with adverse associations found only in the absence the these interactions. Findings also suggest that media verbal interactions may have some direct positive impacts on language development, in that media verbal interactions during the co-viewing of media with educational content (but not other content) were predictive of 14-month language independently of overall level of cognitive stimulation in the home
