3 month old was either rocked or fed to sleep/nap up until this point which worked for us as we all were getting plenty of sleep. I used to be able to transfer DS into the next to me crib once asleep where he would sleep a good stretch of hours. The past few days I cant put him down, he will not sleep unless my breast is in his mouth - he is sometimes sucking but not feeding. Last night I was up for almost 2 hours trying to get him to sleep in his cot after he fell asleep on me after his feed. I don't want to co-sleep as I have tried previously and get even less sleep! He also wont accept a dummy and I cant even use his nap times to catch up on sleep! Anyone had anything similar ?
