I am not sure how big you are talking about but I am an F. ds would just pull his had back the few times he needed to. He also sucks too hard for me to fall out. I know he is asleep or done if he lets go. We put him in his pack-n-play when we go to bed. This gives dh and I some time to be together. Then the 1st time he wakes up I put him in our bed. We started doing this the day we came home. The only problem I've had is dd. We did the same with her and she still wants to get in the bed with us. She has rolled over on ds a few times. He would start squirming and if I didn't get the message he would start crying. I'm afraid she will roll on his head and he will not be able to wake me up. SO, when dd insist she is scared (I can't make her stay in her room by herself if she is afraid) I make sure ds is between dh and me. I don't know if that helps but I hope so.
