At 12 months, many babies do well with about 13.25 hours of total sleep: 11 - 12 hours at night and 2 - 3 hours during the day across 2 naps. Wake windows are typically 3.25 - 4 hours. Nap resistance is common at this age, but most babies aren't ready to drop to one nap until 14 - 18 months. Try extending wake windows before dropping to 1 nap when possible.

At 12 months, most babies walk while holding furniture and some take first independent steps (walking range is 10 - 18 months). Many say 2 - 3 words with meaning and understand far more than they can say. They typically show strong preferences for people and objects, point to request things, and wave bye-bye reliably.

At 12 months, solids take center stage. Babies transition from formula or expressed breast milk to whole cow's milk, and often eat 3 meals plus 2 snacks per day. Growth slows at one year so decreased appetite is normal. Aim to watch hunger and fullness cues rather than portions.

The big shift happens at 12 months: solids become the primary nutrition source and cow's milk replaces formula or expressed breast milk. About 16 oz of whole milk per day is the target.
At 12 months, whole cow's milk (or alternative milk) can replace formula or expressed breast milk. Start with about 16 oz a day — more than 24 oz can crowd out solid food nutrition.
