Is it normal if my toddler wakes up at the same time every night in the middle of the night?

Bad habit: It is if he gets rewarded with a bottle or food. He is getting up as a force of habit, in other words if you set the alarm clock to get up for a ham sandwich, three nights in a row the fourth night you will no longer need the alarm clock to wake you up. Same principle with your child. To stop, let him cry, go to him, but don’t pick him up. After 3-4 nights he’ll stop.
