My one year old has never been a good sleeper but the last couple of nights putting him down in his cot he literally crys his heart out, before this i used to be able to put him down walk out the room.he would have a little moan or play with his teddy then drop off, he then would wake up continuously in the night, but now I'm having this problem with him crying his heart out when I put him down to sleep? anyone got any advice please xo
