What You Need to Know

A 5-month-old baby experiences significant growth in motor skills, communication, and social engagement. According to the Centers for Disease Control and Prevention (CDC), by this age, babies usually can roll over both ways, sit with support, and reach for objects, which are critical components of their physical development.

Evidence-Based Guidelines

The American Academy of Pediatrics (AAP) recommends tracking your baby's development against standard milestones. At 5 months, babies should begin babbling, a precursor to speech, and show recognition of familiar faces and voices. The AAP emphasizes the importance of engaging with your baby through talking and play to support cognitive development.

The World Health Organization (WHO) guidelines suggest that supervised tummy time remains vital for strengthening neck and shoulder muscles, essential for future milestones like crawling. Interaction during playtime is crucial for emotional and social development, as research published in the Journal of Pediatrics indicates.
