H.: My kids are almost all grown up now (18 year old daughter & 15 year old son) however, I made the same mistake with them when they were babies, by allowing them to sleep with me. Even though it's been so long ago, trust me, I remember how hard it was to get them to sleep in their own bed. But, your little girl, at almost 2, should be sleeping in her own room. It's not going to be easy; I had to literally let my daughter cry/scream herself to sleep for about 2 weeks straight. It was painful for me to let her cry, but I knew that in the long run, it was the best thing for her, not to mention me and my husband (he had moved to the couch because he was afraid he would roll over on her when she was an infant). Once they get in this habit, it is a very, very hard one to break; but, again, you know you are not harming her by making her sleep in her own room; she may think she's dying while adjusting! HA--but, trust me, once she knows that you are serious about her sleeping in her own room and not in the marital bed, then she will eventually go to her own bed willingly.
Now, with all of this advice I've just given you, I made the same mistake with my son, who was born 3 years after my daughter and it took me FOREVER to get him to sleep in his own bed.........my husband ended up sleeping on the couch for the last 8 years or so of our marriage--so, for all concerned, it's best if you can get her in her own room at night! Good luck and let me know how it works out!
God Bless,
