Key Takeaways
At 25 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 25 week old baby has strong head control, sits with support (some briefly on their own), and rolls, per the CPS. Steady sitting is a key readiness sign 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 25 week old baby reaches for and grabs objects with control, brings hands and toys to the mouth, and may pass objects hand to hand, per the Canadian Paediatric Society. Picking up an object and bringing it to the mouth is another readiness sign for first foods.
Social & Communication
A 25 week old baby smiles, laughs, babbles and responds to others’ emotions, per the Canadian Paediatric Society. Leaning toward food, opening the mouth and watching you eat are the social readiness signs the CPS lists for starting solids.
FIRST-FOODS SAFETY BASICS
- No honey before 1 year — the Canadian Paediatric Society warns of the risk of infant botulism.
- No added salt or sugar; if using commercial baby food, read the label to check.
- Reduce choking risk: always supervise eating, sit your baby up to eat, cook hard fruits and vegetables to soften them, and slice round foods like grapes lengthwise.
- Once solids start, you can offer water occasionally in an open cup. Small amounts with meals — milk still does the hydrating.
- Wash your hands and your baby’s hands before eating.
GETTING READY
- Have a sturdy high chair, small spoons, and a couple of iron-rich first foods ready.
- Plan iron-rich foods offered at least twice a day once you begin, per the CPS.
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 foods should my baby avoid at 6 months?
The Canadian Paediatric Society advises no honey before 1 year (risk of infant botulism), no sugary drinks or foods, and no added salt or sugar in baby food — read commercial labels to check. Avoid choking-risk foods like whole grapes, hot dog rounds, whole nuts, popcorn and hard candy; slice round foods lengthwise and cook hard fruits and vegetables to soften them.
How do I start solids safely?
Start around 6 months once your baby shows the readiness signs, with iron-rich foods offered at least twice a day, per the Canadian Paediatric Society. Begin with a teaspoon or two, follow your baby’s cues, and never coax. Always supervise, sit your baby up to eat, and offer smooth or soft textures. Introduce one new common allergen at a time so any reaction is easy to spot.
What should a 25 week old baby be doing?
A 25 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 25 week old baby eat?
A 25 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, with milk staying the main nutrition as they begin.
Will starting solids help my baby sleep through the night?
Not necessarily. Night waking is normal across the first year, the Canadian Paediatric Society notes, and milk stays your baby’s main nutrition as solids begin — so first foods don’t reliably change sleep. A consistent daytime and bedtime routine, and putting your baby down drowsy but awake, help sleep settle more than food does.
