She's nearing 10mo now isn't she?
Tbh BF isn't my forte at all, it might be worth popping over to the BF board if you feel like you might get better advice there?
What I do know is that if she's falling asleep instantly while feeding, it could well be a prop rather than actually hunger iykwim? The second one where she's chatty actually might be a routine issue wrt the A time during the day.
I definitely think feeding 4 times might be a little excessive now if she's back to feeling well in herself. You could try using ssh/pat or back to your usual pu/pd for that first NW and see how it goes?
If we look at trying to reduce the NF's for now maybe one at a time wdyt? So try to resettle for the first one, then be prepared to feed say anytime after 12am for the next one. Every other time she's up, use your sleepy phrase and resettle. It might take a day or two for her to get used to it, but she will especially as you're trying to do that with naps now. I'm going to post a link for you about gradual withdrawal wrt to BT. You're just about there with it, but it helps to have a plan! (Just ignore the bit in the link about wi/wo) xx
