Feeding every 30 minutes to hour..

Megan
My daughter is 6 weeks old and eats all the time.... literally every 30 minutes to hour and has done this for weeks. It's exhausting, I can't even spend time with my almost 3 year old son bc I can't get out of the recliner. Could Her lip tie be causing this, bc she does spill A LOT of milk when she eats. I'm so close to switching to formula, but that makes me feel so guilty and depressed. Idk what to do anymore. I need sleep and I need to be able to care for my other child as well. Advise please.
