My 3 month old used to sleep in his bassinet next to my bed without issue but then he got sick with the stomach bug about a week ago. During that time, he would only sleep if I held him (so I did for three nights so we could both get some sleep). After those three nights, we tried to put him back in his bassinet but he cried, so we let him sleep in bed with us. He's been off and on sleeping in his bassinet and in bed with us for the past few nights. He did sleep all night in his bassinet twice but then the other nights he cried until we put him in our bed. I was okay with this method until last night. I realized that I just don't sleep well when he's in bed with us and I don't think he does either. How can I get him to sleep in his bassinet all night? I'm hesitant to cry it out because he's still so little but something's got to give. I think I'm extra frustrated because he was a great sleeper and slept fine in his bassinet until he got sick and now I feel like we've regressed. Suggestions?
