Thumb sucker !

So my son is 3 months old and he kind it loves sucking his thumb. He is teething, I got him the teething mitten and other teething toys.

Apparently, thumb sucking runs in my husbands family 😂 till 4 years old. I definitely do not want him getting used to it.

Is there anything I can do??

I know it’s normal and he’s teething but I’m a first time mom but I don’t want my son to end up getting used to sucking his thumb as he grows.

Thank you !
