how to stop baby sucking her fingers

She is three months old you do not need to worry about her sucking her fingers it is very normal for her to do this and something that you need to allow her to do. She is learning to self soothe herself and this is a way she can provide herself comfort. In addition it is normal for her to do this developmental wise, she is exploring herself and has discovered she has fingers. Do not try to force her to stop doing this.

I agree with earlier statements that babies explore the world around them by sensing things with their mouth. Their mouth is very sensitive and instead of touching things with their fingers like older children and adults do, they sence with their mouth. This is a phaze and it will pass. The reason why she is sucking her fingers is because she is not yet aware of her body. At the age of 1,5 years old children realize that they are a person, that their body, their voice, etc. belongs to them and that they can do things with it. Sucking her fingers might make her feel good, but she has no clue she is doing it, as odd as that may sound. After a while she will learn and realize that the experience she has when sucking her fingers can be called back by a certain action (lifting her hand, putting her fingers in her mouth, sucking on them). It's a miniature experiment that will help her develope a sence of self and I wouldn't worry to much about it. Happy mylotting!

That's how babies explore when they are very small til their vision & mobility improves they explore the world thru their mouth and their hands. So right now her exploration is thru her mouth and will be that plus other areas as she gets into toddler stages. The only time to worry is if there gets to be a sore on the finger, but I doubt a 3mo would be that agressive sucking just yet. You can try scratch mittens and see if they help but sometimes they'll suck on those to get to their fingers anyway. Either way it's all NORMAL! First time mom I"m guessing ? Just post if you have further questions ;) I've got 3 kiddo's and my youngest is 19mo so I remember alot of the itty bitty stuff still.

Just how dirty do you think a three month old babys fingers can possibly get? Leave her be the few germs she has on her fingers wont kill her and you do know a few germs is good for building up resistant!
