Wow... I could have wrote that post!! Even the same reason that we moved to a bed!! And from the day he got that bed he's been a nightmare!!
At the mo I am pregnant, have another son who is 7 who it is not effecting luckily but I am exhausted so I have been 'accidental parenting' to get him to sleep, anyway possible, I just have not got the energy at the moment to deal with this... he wakes up at night and if we put him back he wakes 30 minutes later so now we just let him climb in our bed but he still keeps us awake
We will have to sort this out soon, when I have some more energy and am less tired I plan to do the walk in walk out but I can see it taking hours, Ive tried it before and it drove me crazy!!
He wasn't a good sleeper as a baby but from 11 months he was put in his cot awake, was a sleep within minutes and slept 11-12 hours, same for the day but 2 hours. It was fantastic, it was the bed that was the problem.
It sounds like you are doing a fab job though, sounds like you have alot more patience than me!!! Harvey also has a 2 hour sleep and I'm wondering if that adds to the problem though I'm certain cutting will not stop the night wakings, the other day he had an hour and still woke in the night!
He was 2 in June so a very similar age also. Ill be watching with great interest ready for my turn!!
Good luck, you'll get the best advice here thats for sure!!!
