7 Month Old Baby: Sitting Up, Solids and First Teeth

Your Baby at 7 Months Old

A 7 month old baby is usually sitting with little or no support, babbling, passing toys hand to hand, and eating solids alongside breast milk or formula. From 7 to 12 months, babies need about 11 mg of iron a day, per the Canadian Paediatric Society, so iron-rich foods matter at least twice daily. First teeth often appear around 6 months. Total sleep is around 12–16 hours with about two to three naps.

Your 7 month old baby is more capable and more curious every week — sitting steadier, reaching for everything, babbling in strings of sounds, and getting the hang of solid food. A first tooth may be on the way, too.

This guide covers what’s normal this month: the developing sitting and hand skills, how solids and iron fit together, teething comfort, and sleep.

Your Life This Month: The Parent Experience

Seven months in, mealtimes are a whole new adventure — messy, funny and a bit of work. Try to keep them low-pressure: offer, don’t push, and let your baby explore food at their own pace. A new food may need ten or more tries before it’s accepted — a refusal isn’t a verdict. Eating together helps them learn.

A more mobile, more social baby also means more supervision and, sometimes, more clinginess at drop-offs or with new faces. That’s development, not a setback. Familiar routines and a calm goodbye help.

If low mood or anxiety has been lingering, please tell your doctor or public health nurse — postpartum depression can develop across the first year and is treatable, the Canadian Paediatric Society notes.

Feeding Your 7 Month Old Baby

At 7 months, solids and milk work together. Breast milk or infant formula stays your baby’s main source of nutrition, with solids building up alongside. Keep breastfeeding as long as it’s comfortable, the Canadian Paediatric Society notes, or keep formula feeding. Use the package instructions for how to prepare each bottle, but let your baby decide how much to take.

Feed your baby sitting upright in a high chair, and stay with them the whole meal. Match the texture to what they can manage — thicker purées and soft lumps now, moving toward soft finger foods — and never feed a baby who is lying back, propped or in a car seat.

Iron is the headline nutrient now. From 7 to 12 months, babies need about 11 mg of iron a day, the Canadian Paediatric Society notes — a big jump, because the iron reserve babies are born with runs down by around 6 months. Keep iron-rich foods coming at least twice a day, and pair them with vitamin C foods to help absorption. After iron-rich foods, you can add vegetables, fruit and dairy foods like full-fat yogurt and cheese. Whole cow’s milk as a drink isn’t recommended until 9–12 months, since it’s a poor source of iron.

If breastfeeding isn’t an option, the CPS advises a store-bought, iron-fortified, cow-milk-based infant formula until 9 to 12 months, when whole cow’s milk (3.25% M.F.) can take over, provided your baby is eating iron-rich foods by then.

A note on formula this month. Iron leads at this stage — the Canadian Paediatric Society sets the 7–12 month need at about 11 mg a day and advises an iron-fortified formula if you formula feed. MOF’s organic HiPP Dutch Stage 2 is a follow-on formula designed for 6 to 12 months, iron-fortified to provide iron, DHA and vitamin D alongside your baby’s iron-rich solids. Formula is a good choice whenever it’s the right one for your family.

Sleep at 7 Months: What’s Normal & How to Help

A 7 month old baby usually sleeps around 12–16 hours in total across nights and about two to three naps, in the range the Canadian Paediatric Society gives for infants aged 4 to 12 months (with an average around 14 hours). Night waking still happens and is normal.

New skills — sitting, pulling up, moving — and teething can briefly disrupt sleep as your baby practises or feels uncomfortable. It usually settles. A consistent daily rhythm and calm wind-down help; the Canadian Paediatric Society suggests keeping a regular sleep schedule as much as possible, and putting your baby down drowsy but awake when you can. Try not to leave your baby in bed with a bottle — it’s a tooth-decay risk, per the CPS.

Safe sleep reminder: always place your baby on their back for sleep, on a firm flat mattress with a tightly fitted sheet and no loose, soft items, in a crib. Keep starting your baby on their back even though they can now roll and move — but 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. Keep the sleep space bare — no bumpers, positioners, pillows, or infant nests and loungers. Lower the crib mattress before your baby can push up onto their hands and knees. Car seats, strollers, carriers, bouncers and swings aren’t safe sleep surfaces; if your baby falls asleep in one, move them to their crib as soon as you can. The Canadian Paediatric Society advises back sleeping lowers the risk of SIDS.
