Not necessarily, at that age, they are discovering their hands and fingers and start to put them in their mouth at a lot, it's really cute imo 😉
My 2 month old has been doing the same 😊
Mines 3months and does the same plus she doesn’t like dummies 🙃
Yes my three month old is chewing on his hands not sucking I think he’s teething and he’s drooling which is kinda new
Ps she’s just been fed xx
