50th percentile (median) on the WHO Child Growth Standards. Healthy babies vary widely around these numbers.
Development at 8 months
Your baby is on the move: many crawl, and some pull up to stand. They understand that things still exist when hidden, which can make separations harder.
What you might notice
- Crawls, scoots or shuffles
- Pulls up on furniture
- Looks for a toy you have hidden
- May be wary of strangers
- Starts to pick up small things between finger and thumb
Feeding
Offer three small meals a day with a variety of foods and textures, including finger foods. Continue breast milk or formula.
Sleep
Separation anxiety can cause more night waking. A consistent bedtime routine helps. Always put your baby down on their back, on a firm, flat surface with no pillows, bumpers or loose blankets. The AAP recommends sharing your room, but not your bed, for at least the first 6 months.
Your checklist this month
- Check your home for hazards at crawling height.
- Keep small objects, button batteries and magnets out of reach.
- Play peekaboo and hiding games.
