Ah Twinkling I am the same with my DS2!
He is also still up at nights at least once but often 2 or 3+ times... I have put it down to teething, growth spurts, colds etc but know it is not hunger as DH has got up with him and not fed him (obv!) and it made no difference...
Last night he was up at 10pm , 2:15, 5 and then finally fell asleep at 6:30. I had not slept (grr) since his 2:15 wakening so was a zombie by 6:30. Then just as I was about to nod off.. DS1 got up at 6:45. To cap it all DS1 had also been up at 5:30?? ...
I am going to try another drastic change to our set up and am going to put DS2 in DH's office in the travel cot. Both boys have shared a room for some time now and it hasn't really been a problem until now as they didn't seem to disturb each other. But we all need some peace now DS1 getting up too... so they will both have separate rooms tonight and DH will sleep on sofa as he has to be up mega early for work tomorrow.
This will leave me on my own with the 2 boys but am just going to have to deal with it. If DS1 gets up he is going to get a chance to go to toilet (as I know if I don't do this he will be up 5 mins later saying he needs to go). Every other time I am going to say nothing and put him back in his bed (the only method that worked when he got up before). As for DS2... who knows!
Wish me luck. Good luck with the book. I have binned the books as I found that they just made me paranoid about stuff.. I managed with DS1 without even flicking thru a book just using common sense and adapting my methods to suit and it worked fine. Didn't try Pantley's book tho...
Getting him to sleep in eve is no probs it is just getting him to stay there!! I am despairing with you lovey good luck...
