i have a 3 1/2 month old baby. she drink a 5 oz bottle about every 2 hours, sometimes sooner. i was thinking about starting her with baby rice cereal. she seems hungry still after a bottle. i read everywhere that you shouldnt start till 4 months old. my doctor reccomends 4 months also. i was just wondering when did you mommies start with the cereal? any bad experiences from starting early? im so back and forth with this...
