Grasping Champion!

Everything within reach gets grabbed, investigated, and put in the mouth. Your baby transfers toys between hands and babbling explodes with new sounds.

Development

• Transfers toys from hand to hand — an important fine motor milestone
• Sits with support and holds their back fairly straight
• Rolls both ways — from tummy to back and back again
• Consonants arrive: "ba-ba," "da-da," "ma-ma" (without meaning yet)
• Recognizes their own name and turns when you call

Growth

• Boys: Average 16.3 lbs / 26.0 in (7.4 kg / 66 cm)
• Girls: Average 15.2 lbs / 25.6 in (6.9 kg / 65 cm)

Sleep

• 12–15 hours per day (nighttime sleep 10–11 hours + 2–3 naps)
• Sleep may stabilize after the 4-month regression
• A dark room and white noise still help

Feeding

• 5–6 feeding sessions per day — short, efficient sessions
• Your baby may show interest in your food, but the WHO and AAP recommend waiting until around 6 months before introducing solids. Talk to your pediatrician about your individual baby
• Vitamin D: Continue with 400 IU (10 micrograms) daily

Good to Know

• Well-baby visit: Around 4–6 months, your pediatrician will check growth and development and give the next round of vaccinations (typically DTaP, Hib, IPV, PCV — second doses)
• Teeth: Many babies get their first teeth between 4–7 months. Increased drooling and gnawing are common
• A cool teething ring can help relieve gum discomfort

Activity Tips

Grab-and-drop play: Give your baby a toy, let them drop it, and watch it fall. Repeat! Your baby is learning about gravity and cause and effect.
