Rolling prep, reaching, and early babbles
Key Milestones to Watch
- ✓ Rolling preparation
- ✓ Reaching
- ✓ Babbling
- ✓ Sitting with support
- ✓ Stranger awareness
At four months, your baby is preparing to roll over. They may be able to roll from side to back, or push hard trying to roll over. Hand movements become more precise as they actively reach for and grab toys within sight and bring them to their mouth.
Babbling begins with vowel sounds like “ah” and “oh.” They show curiosity about their environment and turn to find sounds.

Common Questions
My baby shows no interest in rolling. How can I encourage this?
Rolling typically starts at 4 months but often isn't consistent until 6 months. Encourage by giving plenty of tummy time, placing toys just out of reach to the side, and gently helping baby roll over with your hands on their hips. Most babies roll tummy-to-back first. If by 6 months your baby shows no interest in rolling or can't lift their head well during tummy time, discuss with your pediatrician.
Is drooling a sign of teething at 4 months?
Increased drooling at 4 months is common and often related to oral development rather than actual teething. Babies are discovering their hands and mouths. While some teeth can emerge around 4-6 months, most don't get the first tooth until 6-7 months. Excessive drooling accompanied by fussiness, chewing on everything, and disrupted sleep might indicate teething. Use a clean bib to protect skin and offer safe teething toys if needed.
My baby gets very upset around unfamiliar people. Is this early stranger anxiety?
Stranger anxiety typically emerges later (6-9 months). At 4 months, some babies are simply more sensitive to new faces and environments. This early preference for familiar caregivers is normal. Support by holding baby when meeting new people, allowing warm-up time, and not forcing interactions.
Can I start solids at 4 months if my baby seems interested?
Current guidelines recommend waiting until around 6 months for solids. Signs of readiness include: sitting with minimal support, good head control, loss of tongue-thrust reflex, and showing interest in food. At 4 months, these are rarely fully present. Starting solids too early can increase allergy risk and digestive issues. Discuss with your pediatrician if baby seems unusually ready.
My baby doesn't babble much compared to others. What's normal?
Babbling varies widely. At 4 months, babies should make consonant-like sounds (b, p, m) and experiment with volume and pitch. Some babies are quieter observers. To encourage, narrate everything you do, respond to any sound as if it's meaningful, and give baby 'conversational' turns.
What are the different developmental assessment standards?
Different scales use different percentiles. CDC uses 75% (75% of children achieve by that age), Singapore uses 90% (more conservative), and Chinese National Scale includes detailed test procedures. DaMilestone shows you multiple perspectives—helping you understand if your child is within the normal range rather than just pass/fail.
When should I stop waiting and seek a professional evaluation?
At 4 months, seek evaluation if: baby doesn't push down with legs when feet are on a surface, has trouble moving eyes in all directions, doesn't smile at people, can't hold head steady, or doesn't reach for or bat at toys.
