My 1 year old DS seems to have screamed and cried constantly since he was born. Recently it seems to have got worse, he cries all the time & won't let me put him down even for a moment so makes it really hard to do anything. He eats well (loads!!) but is up once or twice every night and then awake between 5 & 6 in the morning yelling for us. I kept putting it down to teething but not sure whether it is? - the constant crying is really getting me down. I also have a 2.5 year old daughter and she was like a dream compared to this!! Any tips/advice????
