Still not a full nights sleep!!!!'

Well the second night went as follows:
11.45 10 mins crying
2.30 20 mins crying
4.00 20 mins crying and then I think he also woke just after 5 for a few minutes....
So not a massive improvement on the night before. In fact in some ways worse. But after trawling the internet I did find a few people saying that it gets worse before it gets better!
Night 3 was almost dreamy!!
At bedtime he played for a few minutes, then cried for about 10 minutes then slept until 3 when he woke for about 10 minutes then slept until 6!
Unfortunately it didn't last!!
Tuesday and Wednesday night went ok but still not great. He was awake about 10 and 3 both nights then on Wednesday night he was very restless after the 3 o clock waking but when he got up he had pooed at some point so maybe that was why??!!!!
Thursday night was then a complete disaster... He woke up at about 11.30 and seemed to be straining. I didn't want him to sit in a pooey nappy as I thought he would be really restless so got up to change him. Only to find clean nappy.... Then I incurred his wrath for properly disturbing him. Then after 20 minutes of screaming I discovered he had completely soaked his clothes, so had to strip him and change him completely. He screamed through this and then continued to scream for another at least half an hour, he finally fell asleep at about 1.15.... Nightmare. And I felt totally guilty like it was my fault even though I was only trying to do the right thing.... At least after that he slept until 6.15 with a little stir at about 3.
Friday night he woke about 11 and once again was restless for a while and when I went in to check he was again wet through.. Had to change him again so a fair bit of screaming, but once changed he was quick to settle back down and actually didn't sleep too badly after that until about 5.30 anyway!!!!
Just to help, he is definitely cutting his second tooth so is in a bit of pain from that and has very rosy cheeks :-(
We are also starting to try to get him to settle with Mandy,(childminder) and in fact anyone other than me as he has suddenly started to develop a bit of separation anxiety and I really don't want him to be like Rachel was (a total nightmare).
So it's all a little stressful at the moment to say the least!
