My little girl is 14 months old and she currently sleeps in a sleep sack, she has since newborn and she sleeps well and I love the idea as she can't pull these over her face, she's only a tiny girl she is 14 months old but only just gone into 6-9 clothing, my partner keeps saying when are we supposed to give her the cot bed duvet because they say 12m+ on them, I personally don't feel comfortable with it yet as those duvets are still quite big and could easily wrap around her but my partner thinks she'd be fine, what age did you give your babies cot bed duvets?
