Ds2 has been waking 3 hourly since birth. He is now just shy of 4 months old and I'm at the end of my rope. He is exclusively breastfed and is initially put in his cradle to sleep and at some stage of the night I generally bring him into bed with me as its the only way I can get some sleep to keep up with my 2 year old during the day. The co sleeping was going well but lately I have been in so much pain from sleeping in one position all night and most nights I'm hanging off the side if the bed as he has all but kicked me off the bed lol. I really need to get him to sleep longer in his own bed but really don't know what to do. Any tips on how I can get him to sleep for a longer period overnight?
