I wrapped Kaitlyn until she was about 8months old as she just loved it. I actually ended up sewing her a special wrap with arms as she used to get out of it as well. I tried to move her to a sleeping back at around 6months and she was not ready and let me know !. Then at around 8months I tried again and walla ...no issue. Just followed the standard bedtime routine and the transition was easy.

I think all bubs are different - Kaitlyn REALLY loved the wrap.
