great big hugs, MM - you must be exhausted!!

it doesn't sound like you're doing anything wrong. it sounds like she's either wanting you - for comfort - and/or she's growing, and extra hungry.

I wish I had some suggestions to make it easier. goodness knows, it's exhausting at that end of the stick, and I remember well DS's marathon feeds which regularly would be 60-90 minutes because he just took his sweet time ...

but even though I can't make any suggestions, I wanted to give you my hugs and encouragement
