8-Month-Old Baby: Growth, Milestones, and Care Guide

Your 8-month-old baby is more active, expressive, and curious than ever! At this stage, many babies are on the move—crawling, scooting, or trying to pull up to stand. They’re also becoming more social, showing preferences for people, toys, and even foods. This is an exciting time filled with exploration and bonding.


Physical Development

  • Mobility on the rise – Many 8-month-olds crawl, scoot, or roll to get where they want. Some may try pulling up to stand while holding onto furniture.
  • Improved coordination – Your baby can likely transfer toys from one hand to the other and may start practicing the pincer grasp (thumb and forefinger).
  • Teething continues – By 8 months, your baby may already have their first teeth, or they may be arriving soon.

Cognitive Development

  • Object permanence – Your baby understands that things exist even when they’re out of sight, which is why peekaboo is so fun.
  • Problem-solving play – They may try different ways to reach a toy or explore how things work.
  • Memory grows – Your baby remembers familiar faces, routines, and favorite activities.

Social and Emotional Development

  • Stranger anxiety – Shyness around new people can peak at this age, and your baby may cling to you for comfort.
  • Attachment – They may cry when you leave the room, showing signs of separation anxiety.
  • Interactive play – Smiles, giggles, clapping, and babbling help them connect with others.

Feeding at 8 Months

  • Breast milk or formula still primary – Continue about 24–32 ounces per day.
  • Solid foods expanding – Offer a variety of purees and mashed foods, such as fruits, vegetables, yogurt, and small amounts of protein (soft chicken, beans, lentils).
  • Finger foods – Try small, soft pieces of food your baby can pick up to practice self-feeding. Avoid choking hazards (nuts, popcorn, whole grapes).
  • Water introduction – Small sips of water in a baby cup during meals may be appropriate (ask your pediatrician).

Sleep Patterns

  • Nighttime – Many 8-month-olds sleep 10–12 hours at night, though teething or separation anxiety may cause disruptions.
  • Naps – Usually 2 naps a day, totaling 2–4 hours.
  • Sleep regressions – New skills like crawling and standing can make it harder to settle down at bedtime.

Safety Tips

  • Baby-proof thoroughly: secure furniture, block stairs, cover sharp corners, and keep small objects out of reach.
  • Lower crib mattress if your baby is pulling up.
  • Always supervise mealtimes and play.

When to Talk to Your Pediatrician

Every baby develops at their own pace, but check in with your doctor if your 8-month-old isn’t showing interest in rolling, sitting without support, or engaging with sounds and people.


Your 8-month-old is full of personality and determination. They’re eager to explore the world, test their independence, and interact with you in new ways. This stage may feel busy, but it’s also one of the most rewarding as your little one’s unique character shines through.
