thanks for the support folks, its much appreciated.
but first things first, we tried all the advice at the weekend and two things happened:
1. we put jack down to nap on saturday morning around 9.30 and suprisingly with no fuss he slept soundly for two hours. we tried a gain as suggested at 2.30 and we got 1 1/5 hours with no fuss, so all going well.
the same happened on sunday with the nap routine, taking two hours each time with no fuss
2. then saturday night, we had the worst night ever, he woke at 9, 10, 11, 12 (for two hours), 3, 4, 6
and as for last night, he woke at 9, 10, 11, 12, 2 ( gave up and brought him in the big bed).
any advice please!!!!!!
