4 month regression?

B✨

My babe has been having trouble sleeping all of a sudden, she’s gassy as well which is new. It’s like she’s a brand new baby all over again. I assume this is the 4 month regression. But she’s also crabby during the day, always wanting to nurse nonstop or chew on my fingers/anything she can grab. Is this part of the regression or teething? Is this normal? I’m going crazy lol she doesn’t want to nap for more than 15 minutes usually and she wants to stay latched on the whole time 😫 hard to do anything lately
