Key Takeaways
At 24 weeks, most babies have the 3-month skills the Canadian Paediatric Society describes and are close to the end-of-8-months set.
Physical Development
A 24 week old baby has strong head control, sits with support (and some sit briefly on their own), and rolls, per the CPS milestones. Many babies are rolling both ways around now — front to back and back to front. Sitting steadily is one of the key signs of readiness for solids, which the Canadian Paediatric Society describes around 6 months. Keep up supported sitting, on the floor and always close by, and daily supervised tummy time — three sessions of 10 to 15 minutes.
Hands & Hand-Eye
A 24 week old baby reaches for and grabs objects with control, brings hands and toys to the mouth, and may pass an object hand to hand, per the Canadian Paediatric Society. Being able to pick up an object and bring it to the mouth is another readiness sign for solids.
Social & Communication
A 24 week old baby smiles, laughs, babbles and responds to others’ emotions, per the Canadian Paediatric Society. Showing interest when others eat — leaning in, opening the mouth, watching your food — is a social readiness sign the CPS lists for starting solids.
GETTING READY FOR SOLIDS
- Set up a sturdy high chair with good back support and a couple of small spoons.
- Plan iron-rich first foods — the Canadian Paediatric Society advises starting with foods that contain iron, offered at least twice a day.
- Watch for the readiness signs together: sitting with support and good head control, bringing food to the mouth, holding food without pushing it out, and interest when others eat.
DEVELOPMENT & PLAY
- Keep up supported sitting and daily, supervised tummy time to build the strength behind sitting.
- Offer safe toys of different textures to grip, pass and safely mouth.
- Keep small objects, cords and choking hazards out of reach.
FEEDING & SLEEP
- Keep feeding on cue; follow your formula’s feeding chart for amounts.
- Give breastfed babies a daily 400 IU vitamin D supplement, per Health Canada and the CPS; formula-fed babies don’t need one.
- Keep the three-nap rhythm and practise safe sleep every time.
Frequently Asked Questions
What are the signs my baby is ready for solids?
The Canadian Paediatric Society lists these readiness signs, usually around 6 months: your baby can sit up with support and control their neck muscles, can pick up food and try to bring it to the mouth, holds food in the mouth without pushing it out, shows interest when others eat, and opens their mouth when food comes. Look for several signs together, not just one.
Can I start solids at 24 weeks (almost 6 months)?
Some babies are ready a few weeks before 6 months, the Canadian Paediatric Society notes. If your baby shows the readiness signs — sitting with support, good head control, bringing food to the mouth, interest when others eat — you can begin, starting with iron-rich foods. If not, waiting a week or two is fine; aim for around 6 months and not long after, since waiting raises iron-deficiency risk.
What should a 24 week old baby be doing?
A 24 week old baby usually has strong head control, sits with support, rolls, reaches and grabs with control, brings things to the mouth, and is social — smiling, laughing, babbling and responding to your emotions, per the Canadian Paediatric Society. Every baby develops at their own pace; raise concerns, especially in more than one area, with your doctor.
How much should a 24 week old baby eat?
A 24 week old baby feeds on cue — the Canadian Paediatric Society advises feeding on demand. Amounts vary a lot; follow the feeding chart on your formula’s packaging. Plenty of wet diapers and steady weight gain show your baby is getting enough. Solids are recommended around 6 months.
How much sleep does a 24 week old need?
By 4 months, the Canadian Paediatric Society notes, most babies need three naps a day — morning, afternoon and early evening — with total sleep around 14–16 hours across naps and nights. Every baby differs, and night waking still happens. A regular daily rhythm and calm wind-down help sleep settle.
