What you're likely noticing is their emerging ability to calm themselves, follow movement with their eyes, and begin to recognize your voice and face. Around this age, babies start showing the very beginnings of social awareness, though genuine smiling typically arrives closer to 8 weeks.\n\nThe most important thing at 5 weeks is simply that your baby is feeding, gaining weight, and you're getting to know their rhythms. Development in these early weeks looks quiet from the outside—lots of sleeping, eating, and slowly learning to focus. Every baby's timeline is genuinely different here, so there's real flexibility in what \"normal\" looks like. If you have specific concerns about feeding, breathing, or anything that feels off to you, your pediatrician is always the right person to check in with at your regular visits.\n\nYou're doing great noticing and thinking about where your little one is at.","sources":"[{\"title\":\"Infant and Newborn <span class=\\\"qt1\\\">Development</span>\",\"journal\":\"NIH MedlinePlus\",\"year\":\"2026\",\"url\":\"https://medlineplus.gov/infantandnewborndevelopment.html\",\"label\":\"RELEVANT\",\"score\":0.774},{\"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\":0.732},{\"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\":0.724},{\"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\":0.721},{\"title\":\"Stability of developmental milestones: Insights from a 44-year analysis.\",\"journal\":\"Infant behavior & development\",\"year\":\"2024\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/37976937/\",\"label\":\"RELATED\",\"score\":0.72}]","view_count":0,"created_at":"2026-07-11T00:44:28.854Z"}
