Baby comfort nursing all night?

My daughter is 9 days old today and the past couple days she's had a really hard time sleeping her usual 2-3 hours at night between feeds unless she's latched to me. I don't mind comfort nursing but I'm worried she's getting stomach pains from over eating. She was interested in her binkie before to help her stay asleep but now she just wants to be with me. I love all the snuggles but I can't sleep at all during the night anymore as she's up within 30 minutes if I try and sneak her into her bassinet after a feed. What should I do?
