hello all, thought I'd post an update.
the method of moving jack in and out of our bed worked well for a few months, but he soon reverted to type and began waking up during the night again.
we have just been away for new year with friends and family, and due to a booking error, jack had to sleep in with us for a week, subsequently it is as if we have travelled back in time and he is worse than ever, waking every two hours in his own bed until he gets what he wants and is allwed in our bed, this coupled with the youngest going through a spell of teething equals no sleep at all.
what made it worse was whilst away, a friend child, was the best sleeper i have ever seen, they would bath bottle put to bed, lights of close the door, then walk away and you would hear this 2year old playing around and amusing himself and then eventual going to sleep with no fuss, sleeping all night till 8.30 the next day.
on asking they advised "oh we just let him get on with it" and "he cried it out for two weeks which where hard but it was Worth it".
this made us look very deeply at our problem, with one of us missing most of the night spent consoling a non sleeper, we may have to reconsider drastic action.
anyway, thankyou for all your posts, i doubt anyone will still read this, who wants to hear me moaning on all day?
