How long ago did you make the changes? It does take awhile for them to adjust to a new "routine" or a small change to the existing routine.

I don't have any real answers for you - but HEAPS of support as DS#1 was a shocking sleeper and didn't start sleeping through the night until he was three. At 17 months he was still waking frequently despite my refusing to give him boobie in the middle of the night.

The only suggestion I would offer is to ask how much time she spends outdoors playing? I find that if DS#1 spends about an hour outside enjoying physical play he often sleeps better at night. DH and I have been taking the boys to the park after dinner for about an hour and then we come home and put them to bed.

He will be four in February and he usually wakes at least once at night to do a wee, and once or twice a week he comes in our bedroom around 4am so he comes into bed with us usually.

This is a HUGE improvement to the old days.

As I said, not a lot of answers for you, but hopefully some support. I will watch this thread to see how you go.
