My daughter is almost 12 months old and she will not sleep on her own. She is slowly getting better, up until about 2 months ago, she would only fall asleep while i was feeding her. But now she is happy just going to sleep in my arms (most of the time anyway.) I have a son also who is 2 years old and they share a room. How can I teach my baby self settling without distrupting my sons routine? Also my fiance has a hard time with her crying (even if it does help in the long run) How can I make it so that all 3 parties are happy?
