so we just switched my son to his toddler bed (he'll be 21/2 next month). When we made the switch i also took away his sleep sack. I'm now realizing i should have taken it away earlier. He keeps asking for the sleep sack (it's too small) and won't sleep under the blankets we got him. They are even Cars,his favorite. Every night he wakes up in the middle of the night upset because he's cold, but he freaks out if you try to put the blanket on him. I think I read I could probably find a XL sleep sack somewhere, but i feel like it's time for him to separate from the sleep sack! Has anyone else had a child who doesn't want to get under the blankets? I'm hoping he'll change his mind eventually . . .
