How can I make my one year old son sleep though the night? I feel stress wherever midnight he will wake up for milk and worst even play around one / two hrs and he wake 6-7 am :(

cut down on electronic devices before bed time. 1yo usually won't sleep thru the night yet. the wake up time is pretty normal to me. you can consider putting some rice cereal into the milk to thicken it make them more full to sleep longer
