changing night waking times

[Stokey]

A pattern seems to be emerging in my 9 wk old sleeping. She seems to wake at 2.30 and 5.30 regardless of what time i have fed her. Have tried putting her down around 7.30pm unsuccessfully, she normally finally settles 8.30-9. But she wakes up around 2.30 whether i feed her at 9 or 11.
So any suggestions as to how i can get her to do 11-4.30, rather than 9-2.30? Dd1 normally only goes off to sleep around 8, then we have dinner, so not really practical for me to go to sleep at 9 too
Haven't got much discipline day sleeps yet and she still feeds every 2-3 hours during day. Was born at 36 weeks so weighs around 10.5lbs so still small.

Honestly? Let her go down at 9 and go to sleep then yourself. Don't worry about it, she is still ever so little and will have changed her sleep pattern completely within another month so just go with it

I don't think there is anything you can do to change a 9 week olds waking times. They are still so young and things will likely change on a weekly basis! If I am honest I think you are doing pretty good to have a 9 week old that is only waking once a night ( I would class 5.30 as morningand when mine often want to get up for the day!!) Can't you have your dinner earlier so you can go to bed 9ish. It won't be forever.

Yes, you're right, and after writing this last night she went from 11 to 3.45, which was great, so am hopeful this will be a new dawn.
Think was spoilt as my oldest slept so well that i used to have to wake her to feed in first few weeks.
