Not realizing it, my DS (10 weeks) was comfort sucking himself to sleep on me. While I've gotten better at recognizing his sleep signs, I didn't realize he was doing this until the past week or so. On the advice of the HV today I've tried to not let him do it tonight and get him into bed a lot earlier than "normal" (when he was comfort sucking himself on me). With the exception of two 10 minute sleeps, he's been almost non-stop crying/screaming for almost four hours. I have changed him, fed him (as it was around the time he would normally eat and was showing genuine hungry signs), rocked him and used all of the tips the HV gave me. He's been crying for so long/so hard at times that he's gotten himself so hot I've had to peel a layer off of him (his sleeping bag). How much longer can this go on? Any other tips?
