Hi
When I started PD at 11 months, my baby was about the same, except didn't even have that 3 hour streach in the beginning of the night !
I finally couldn't take it anymore so I started PD.
It has taken a long time. I have a spirited LO and it seems to me that all the accidental parenting coupled with the age, it takes a long time.
You are right when you attribute it to age. They have had 11 months of reinforcing these behaviors from us. So, it going to take a bit of time. Longer depending on the temperment of your baby. I was doing nothing exciting when he woke up either. Now he does not even come out of his crib, (unless he is having a night terror and I need to comfort him-but he goes right back in). Nevertheless he still often wakes up. I think when he realized he still is not getting what he wants when he wakes up (even though it's been 3 months) that makes him upset.
Is she getting enough food in the day?
Is she on EASY?
Hang in ther and be persistant, consistant and patient in the night in terms of PD so she knows night is night in her crib. Is she in her own crib? You mentioned laying with her to nurse her to sleep.
let me know if that helps,
melissa
