This period marks the full transition into toddlerhood. Walking is now established and babies are testing independence enthusiastically. Language is accelerating, with a vocabulary of 5-20 words by 15 months. Toddlers begin to understand 'mine' and assert themselves, which can lead to early power struggles. Feeding expands to include almost all family foods.
