Sleep training for 16 month old
I have a 16 month boy who has been in my care since 12 months. He was very very attached to mom and cried the first 3 weeks straight. He is now very attached to me and will cry if i even leave the room to pee. Up until now he has been sleeping with me holding him then putting him on a little spiderman pull out couch. I really want to get him to sleep in a playpen upstairs so i can do my dished and tiding without waking him. Problem is he is going to cry non stop. My question is is it okay to let another persons child Cry It Out? and to what extent? any suggestions?
