Re: nursing aaaaaaaaaaall night long!
My daughter does the exact same thing, some time I disconnect the latch if I need to change positions or she moves herself eventually. My pediatrician is not a fan of the cosleeping and eating during the night (response I got when I said it didn't bother me was "you want to get her on a schedule, surely you don't want her just eating through the night, you'll get tired") so I don't bother anymore to discuss it in our appointments. My feeling is, if it works for your family and is not causing harm to your child continue. I know for me I am well rested, at ease and maintaining a meaningful connection to my daughter by co-sleeping and letting her eat on demand during the night.
