DS has never been a good sleep but about a month ago we thought we'd cracked it - for about a week!
Now we are back to waking a couple of times in the night crying. DH goes in and picks him up, hugs him and he goes back to bed okay, but understandably DH is getting mightily fed up with getting up in the night and we're both tired from the broken sleep. If we leave him he just escalates, likewise if we go in but don't pick him up.
Help please - two years of broken sleep is taking it's toll on us. :(
