Hi Julie
Do you know why he`s waking up? Is is habit, not being active enough during the day, night terrors? Just a thought but maybe if you can pinpoint a reason then you can look at sorting that out? Ours just likes to be cuddled, and wants the comfort of mum and or dad whilst he`s nodding off and when he`s asleep.
Then there`s the controlled crying technique..... It does work but I don`t like doing it, whilst I`m counting the minutes I have to be doing something or I just go in to Oliver.
Its all worth considering, but at least you know you aren`t the only mum who has been through this.
Oh another thought how many people have said its just a stage and it will pass? I throttled the last one that told me that. It was after 4 weeks of not sleeping through.
