Baby can stand alone, possibly for a few minutes. She drinks from a cup. She expresses herself with gestures and sounds instead of cries. Baby can roll a ball to you. She uses gibberish in a conversational way.
All babies have their own internal developmental timetable.
If you have concerns about your baby's development, discuss them with her doctor. Fancy footwork Shoeless is cool. You may wonder what's the appropriate footwear for your newly mobile baby. Most doctors recommend nothing. But if you're looking for protection while you're outdoors, choose low-cut baby shoes with flexible soles, flexible uppers, flat nonskid bottoms, and a roomy fit.
