hi. are you getting on any better? i think it's normal i'm afraid. don't compare with your neices, they're all different and you'll end up driving yourself crazy!
i agree she could be waking from habit as well as hunger but that's what comes with breast feeding. they also like the closeness. your doing well stick at it. mine was 4mth when i weaned as she was a hungrey baby. it helped no end. but i found she still woke alot more than bottle fed babies so did my 2nd. try giving more rice in the day half way through her feed it will help a little at night but you may find the next problem is stopping the habit of waking. it's hard to tell which it is when your weaning.
i expressed but didn't bother with my 2nd. i found it really time consuming and it didn't make much difference in the end. with both i fed untill around 15mth while i weaned straight onto cows milk so it really is worth it. stick at it!
if your comfy with it she could go in her own room, if she's not allready. you wont hear her so much on the monitor so sometimes she may settle herself and she won't wake to look round to your bed for you. she'll scream if she wants you!
