My DS is 18 months and still in sleeping bags. He doesn't like them and cries when we get it out at bedtime. With the weather being hotter, we've just been putting him down and putting a cellular blanket over him which has been great and he's slept really well, so I think we're done with sleeping bags. Starting to think about a little, light duvet (no pillow as he's never had one so doesn't miss it!) but don't know if I should? What do your toddler's sleep in/under? Any recommendations?
