This is also a great time when they're becoming more engaged—they're starting to track movement with their eyes and responding more to your voice and face.\n\nOf course, every baby develops at their own pace. One baby might babble away while another is quieter, and both are completely normal. What matters is that they're progressing in their own way across the different areas of development—movement, fine motor skills, language, and social connection.\n\nIf something feels off to you or you're curious about where your baby sits developmentally, your pediatrician is the best person to chat with at your next check-up. Trust your instincts about your own baby.","sources":"[{\"title\":\"Infant and Newborn <span class=\\\"qt1\\\">Development</span>\",\"journal\":\"NIH MedlinePlus\",\"year\":\"2026\",\"url\":\"https://medlineplus.gov/infantandnewborndevelopment.html\",\"label\":\"RELEVANT\",\"score\":0.761},{\"title\":\"Uncoupling of the Infancy Life History Stage.\",\"journal\":\"Hormone research in paediatrics\",\"year\":\"2021\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/34352793/\",\"label\":\"RELATED\",\"score\":0.752},{\"title\":\"CDC — Developmental Milestones (Part 2 of 4)\",\"journal\":\"CDC Clinical Guidelines\",\"year\":\"2023\",\"url\":\"https://www.cdc.gov/ncbddd/actearly/milestones/index.html\",\"label\":\"RELATED\",\"score\":0.747},{\"title\":\"Breastfeeding and motor development in term and preterm infants in a longitudinal US cohort.\",\"journal\":\"The American journal of clinical nutrition\",\"year\":\"2017\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/29092884/\",\"label\":\"RELATED\",\"score\":0.73},{\"title\":\"Walking Attainment in Very Low Birth Weight Infants in Japan.\",\"journal\":\"Physical therapy research\",\"year\":\"2021\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/35036253/\",\"label\":\"RELATED\",\"score\":0.725}]","view_count":0,"created_at":"2026-07-11T13:13:08.039Z"}
