Activities to try this week

Tummy time with toys

10-15 min, 2-3x daily

Place colorful toys just out of reach during tummy time to encourage reaching and pushing up. Builds neck, arm, and core strength for crawling.

Mirror play

5-10 min

Sit with baby in front of a safe mirror. Point to features ("nose!", "eyes!"). Builds self-recognition and language.

Babble back

Throughout the day

When baby babbles, repeat the sounds back as if having a real conversation. Pause for them to "reply." Builds turn-taking and language foundations.

Texture basket

10 min

Fill a basket with safe items of different textures — silk scarf, wooden spoon, soft brush. Let baby explore. Builds sensory awareness and fine motor skills.

Sit and reach

5-10 min

Support baby in a sitting position with a U-shaped pillow. Place toys in front so they reach forward. Strengthens core for independent sitting.

Common questions

How much should a 6-month-old eat?

Most 6-month-olds drink 24-32 oz of breast milk or formula per day, plus 1-2 small servings of solid food (2-4 tablespoons). Always follow your pediatrician's guidance for your baby.

How much should a 6-month-old sleep?

Typically 14-15 hours total: 10-11 hours at night and 3-4 hours of daytime naps, usually split across 2-3 naps.

When should I worry if my 6-month-old isn't sitting up?

Babies develop at different rates, but if your baby can't sit with support, doesn't push up during tummy time, or seems very floppy, talk to your pediatrician. Early support makes a big difference.

Should my 6-month-old be crawling?

Crawling typically starts between 7-10 months, and some babies skip it entirely. At 6 months, focus on tummy time and pushing up — these build the strength needed for crawling later.
