Week 24 is one of those weeks that feels like everything changes at once. Your 24 week old baby may be sitting up without support for the first time, tasting real food beyond breast milk or formula, and possibly cutting a first tooth — all in the same week. At six months, your baby's world is expanding rapidly. They are stronger, more curious, and suddenly very interested in everything happening around them. As a parent, I remember week 24 feeling like a turning point — my baby went from content observer to active participant almost overnight. This guide covers exactly what to expect and how to support every milestone.
Quick Answer
At 24 weeks (6 months), most babies begin sitting independently, start solid foods, and may show first teeth. Increased mobility means they are ready for more floor time on safe, supportive surfaces that cushion inevitable wobbles and tumbles.
What's Happening at Week 24
Week 24 marks a significant developmental leap across every domain. Here is what is unfolding:
Physical Development
Your baby's core strength has been building for months, and now it pays off. Many 24-week-olds can sit unsupported for several seconds to a minute, though they still topple frequently. The American Academy of Pediatrics (AAP) notes that most babies sit with minimal support between 4 and 7 months. Some babies are also beginning to push up on hands and knees in a pre-crawling position, rocking back and forth.
Feeding Milestones
The AAP and the Centers for Disease Control and Prevention (CDC) both recommend introducing solid foods around 6 months, when babies can hold their head steady, sit with support, and show interest in food. Week 24 is typically when pediatricians give the green light. Start with single-ingredient purees or soft foods and introduce one new food every few days.
Oral Development
First teeth — usually the lower central incisors — often appear around this time. Signs include increased drooling, gum rubbing, and mild fussiness. Cold teething rings and gentle gum massage can help.
Cognitive and Social Growth
Your baby now recognizes familiar faces at a distance, responds to their name, and babbles with vowel-consonant combinations like "ba" and "da." They are also developing object permanence — the understanding that things still exist even when hidden.
Best Activities for Week 24
These five activities are perfectly matched to your baby's current abilities:
1. Supported Sitting Practice
Place your baby on a soft surface and arrange pillows or a nursing pillow around them. Let them practice balancing while you stay within arm's reach. Each session builds core strength and confidence.
2. First Food Exploration
Offer soft purees on a small spoon or try baby-led weaning with appropriately sized soft foods like avocado strips or steamed sweet potato. Let your baby touch, smell, and taste at their own pace — mess is part of the learning.
3. Peek-a-Boo Games
This classic game directly supports the object permanence skills developing at week 24. Hide your face behind a cloth, then reveal yourself with an enthusiastic voice. Vary the timing to keep it exciting.
4. Reaching and Grasping Stations
Place colorful toys just slightly out of reach while your baby is on their tummy. This encourages reaching, pivoting, and the early movements that lead to crawling. Rotate toys to maintain novelty.
5. Mirror Play
Prop a baby-safe mirror at floor level. At 24 weeks, babies are fascinated by faces — including their own. This activity supports social-emotional development and tummy time simultaneously.
Creating the Right Environment
With your baby sitting up and starting to move, the play environment matters more than ever. Hard floors are unforgiving when a newly sitting baby tips sideways — and at week 24, tipping is constant. A cushioned play surface absorbs impact and gives your baby the confidence to practice sitting and reaching without pain from falls.
The PocoKoko memory foam play mat provides the ideal balance of firm support for sitting practice and soft cushioning for inevitable tumbles. The high-density memory foam is thick enough to protect against falls but stable enough that it does not interfere with your baby learning to balance. Unlike thin foam tiles that shift apart, a one-piece mat stays securely in place as your baby moves across it.
As your 24-week-old grows more mobile, consider setting up a dedicated floor play area with a crawling mat that gives them room to pivot, rock, and eventually crawl.

When to Talk to Your Pediatrician
Every baby develops on their own timeline, and week 24 falls within a wide range of normal. However, the CDC recommends contacting your pediatrician if your baby does not bring objects to their mouth, does not reach for nearby toys, shows no response to sounds or voices, or cannot hold their head steady when supported in a sitting position. Difficulty with feeding or persistent refusal of solids after several attempts is also worth discussing. Trust your instincts — you know your baby best.
FAQ
Can a 24 week old baby sit up on their own?
Many 24-week-old babies can sit independently for brief periods, though they still need a cushioned surface nearby for safety. The AAP considers sitting with minimal support typical between 4 and 7 months, so some babies may need a few more weeks of practice.
What foods can I give my 24 week old baby?
At 24 weeks, start with single-ingredient purees like sweet potato, avocado, banana, or iron-fortified baby cereal. Introduce one new food every 3-5 days to watch for allergic reactions. The AAP recommends starting solids around 6 months when babies show developmental readiness signs.
Is it normal for a 24 week old to not crawl yet?
Yes, this is completely normal. Most babies do not begin crawling until 7-10 months. At 24 weeks, your baby may be rocking on hands and knees or pivoting on their tummy, which are healthy pre-crawling movements. Some babies skip crawling entirely and move directly to pulling up and cruising.
