Anybody else's baby a thumb sucker? She's refused pacifiers since we left the hospital, she's ebf (even though she's ebf I've still tried to give her a paci just because it felt like she was eating a ton & literally attached at all times- also she will take a bottle if needed but that's not often as I'm a stay at home mom). Now she's 12 weeks old, we've got a good schedule down, she sleeps through the night but she's picked up on a thumb sucking habit. I thought maybe she would be hungry so I would go to feed her & sometimes she would take it (obviously hungry) then other times she would get mad & only want her thumb. Is that normal? None of my kids took pacifiers really except in the first few weeks & even then they didn't like them but none of them had a thumb sucking habit lol. (although my 2nd did in the womb, we got a good picture of it at my 15wk ultrasound) but none of them did it outside of the womb. Should I be concerned or is this normal?
