My baby girl who is almost ten weeks all of a sudden started sucking on her fist. It’s super funny and cute because she is seriously just going at it, smacking noises and everything🤣. I tried giving her the boob and she doesn’t want and she’s never been a huge fan of pacifiers. Should I just let her keep doing this or is there a reason why? I don’t want her do suck her hands too much and get them irritated 😐

She used to chew on her hands before when she was hungry to calm herself down for a little while but now it’s like allll the time
