Eating too often?

How often should a 10 week old nurse and for about how long? No matter how hard I try my baby will not stay awake (and I mean we have tried it all.) and the few times she has stayed awake she is done after 10 or so minutes total. This is causing her to want to eat every two hours or less. Which means she is only sleeping for 30-40 minutes at a time. This doesn’t seem right and I want to help her get back on track so any suggestions would be greatly appreciated!

I think I might have a slight bit of an oversupply on one side based on her moving off the breast and getting sprayed in the face and she also chokes quite a bit. To say we are a bit of a mess is an understatement 😂
