Sleeping while breastfeeding

Ftk

Hey guys, I have a 3 week old baby girl, she's always wanting a feed, I mainly breastfeed with a bottle of top feed at night. Everytime she latches, she's asleep within 10, 15 minutes. There's a suck every 2 mins while she's asleep but this takes forever. She goes through 6 dirty diapers a day so it's just about keeping her awake.

P.s. I've tried tickling her feet and ear, swaddling her, not swaddling her, nothing seems to work! Help!!!
