Hello my son is 1. Couple weeks ago i put the side down on his cot so that it could be an extension to my bed. Waste of time. Ill put him in his cot maybe an hour later hes awake and i just put him in my bed purely due to my overtiredness!!! He still wakes in the night for a milk. This morning he woke at 4am. Ive had this week off work purely to sleep while hes at nursery. I cant cope with this broken sleep. How do i progress. What do i need to do? Why wont he sleep in his cot? Any advice greatly appreciated
