Key Takeaways
At 26 weeks — 6 months — most babies have the 3-month skills the Canadian Paediatric Society describes and are moving toward the end-of-8-months set.
Physical Development
A 26 week old baby usually has strong head control, sits with support (many briefly on their own), and rolls, per the CPS. Steady sitting and good head control are exactly the signs the Canadian Paediatric Society lists as readiness for solids. Sitting on their own comes over the next couple of months, among the CPS end-of-8-months milestones.
Hands & Hand-Eye
A 26 week old baby reaches for and grabs objects, brings them to the mouth, and may pass objects hand to hand, per the Canadian Paediatric Society. That grab-and-mouth skill is what lets your baby start to pick up and explore first finger foods.
Social & Communication
A 26 week old baby babbles, laughs and responds to others’ emotions, per the Canadian Paediatric Society. Mealtimes become social: your baby loves being included at the table, and shows likes and dislikes for foods, which the CPS notes begins around 6 to 9 months.
DEVELOPMENT & PLAY
- Offer supported sitting with cushions or your hands, always on the floor and always close by, so your baby can practise balance and take in the room. A propped baby topples sideways without warning — on a sofa or bed, that’s a fall.
- Offer safe, grippable toys of different textures to reach for, grab, shake and safely mouth. If teething is starting, a solid silicone or rubber teether is the safe option — skip amber teething necklaces and bracelets. Health Canada warns against them: the cord is a strangulation risk and the beads a choking one, and there’s no evidence they relieve pain.
- Keep up daily, supervised tummy time to build trunk and shoulder strength for sitting.
- Keep small objects, cords and choking hazards out of reach, and never leave your baby alone on a raised surface.
ROUTINES & SLEEP
- Lean into the three-nap rhythm the CPS describes, with a calm, consistent wind-down.
- Keep days bright and active, nights calm and dim.
- Practise safe sleep every time, and keep starting your baby on their back even once they can roll. If your baby rolls onto their front on their own, you don’t need to turn them back — that’s safe once they can get there under their own strength. Your job is the starting position and a bare crib; the rest is theirs.
FEEDING & HEALTH
- 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. Combination-fed babies need one too — they don’t take enough formula to cover the requirement. Exclusively formula-fed babies usually don’t, since vitamin D is already added to formula.
- Solids are coming soon — but wait until around 6 months. We’ll cover readiness signs in the weeks ahead.
Frequently Asked Questions
How do I start solids at 6 months?
Start with iron-rich foods — meat, poultry, cooked whole egg, fish, tofu, well-cooked legumes, or iron-fortified infant cereal — offered at least twice a day, per the Canadian Paediatric Society. Begin with a teaspoon or two, follow your baby’s cues, and offer a variety of textures. Keep breastfeeding or formula feeding alongside. No honey before 1 year, and no added salt or sugar.
What are the best first foods for a 6 month old?
The Canadian Paediatric Society recommends starting with iron-rich foods: puréed, minced or diced meat, fish or chicken; tofu; mashed beans, peas or lentils; eggs; or iron-fortified infant cereal. Healthy foods your family already eats are a good choice too, with no added salt or sugar. Offer iron-rich foods at least twice a day, and introduce vegetables, fruit and dairy foods after that.
Should I stop formula or breast milk when starting solids?
No. At 6 months, solids complement milk — they don’t replace it. Breast milk or infant formula stays your baby’s main nutrition through the rest of the first year, the Canadian Paediatric Society notes. Keep breastfeeding or formula feeding on cue alongside first foods, and let solids gradually increase over the coming months.
How much solid food should a 6 month old eat?
Start small — a teaspoon or two — and follow your baby’s cues, the Canadian Paediatric Society advises. Some babies need to try a food many times before accepting it. Never coax your baby to eat more; if they turn their head or close their mouth, they’re finished. Milk stays the main nutrition, so there’s no rush to increase amounts.
Can I give my 6 month old peanut or egg?
Yes — you can introduce common allergenic foods like peanut and egg around 6 months when you start solids, per the Canadian Paediatric Society. Offer one new food at a time so any reaction is easy to spot, make sure the texture is smooth and safe (thin peanut butter with water or purée), and keep offering it a few times a week if tolerated. Talk to your doctor if your baby is at high risk of allergy.
