Your baby now loves to play games. He'd rather not go to sleep. He can stand while holding on to someone or something. He can walk while holding onto furniture.
Baby drinks from a cup.
He can stand alone for a few seconds or perhaps longer. All babies have their own internal developmental timetable. If you have concerns about your baby's development, discuss them with her doctor. At 9 months, he may start to wean himself from a morning nap. Be supportive, unless he just can't make it to lunchtime without being fussy and overtired.
