baby addicted to breast

Nicole
At home after being awake for an hour and 15 minutes maybe if he starts to cry and the only thing that soothes him and puts him to sleep is the breast. When doing tummy time he tries to latch the mat and when I lay him down in the crib he tries to latch the crib mattress.
At daycare they say he can be awake all day and they've never seen him try to latch anything. When I picked him up one day he was crying because he wanted to breast-feed and they said they've never seen him cry like that before. 
As soon as we get home from daycare all he wants to do is sit on my breast all night. Even after a day at daycare where he sleeps most of the day.
