Everything below is written for breastfeeding.

Months 12–23 · one-glance sheet

Year 1

The baby stage is over on paper, even if it doesn't feel that way yet. Walking, first words, and real food arrive on their own timeline.

1
Well-child visits at 12, 15, 18, and 24 months
Each one includes a milestone check — bring any concerns, even small ones.
2
Toddler-proof at floor level
Once they're upright and mobile, choking hazards and unsecured furniture become the top safety issue.
3
Whole milk, not formula or unlimited breastmilk
Most toddlers are transitioning off formula and bottles this year, at their own pace.

for stopping

There's no age at which breastfeeding stops being appropriate. Keep going as long as it works for both of you, alongside regular food.

Draft figures for this age, pending clinical review.

Trust the worry. None of this is an overreaction.

No single words by 18 months, or no meaningful two-word phrases by 24 months.
Loss of a skill they used to have — words, gestures, or physical skills — at any age.
Not walking independently by 18 months, or a very asymmetric gait.
A temperature above 104°F (40°C), or a fever with unusual drowsiness, rash, or stiff neck.
Choking, a swallowed object, or any injury followed by vomiting or loss of consciousness — treat as urgent.
