How to discourage a 4 mth old from thumb sucking

DS use to do this off and on at the same age and honestly it did not worry me. He doesnt do it now at all. I think at that age its them just starting to explore their tastes. I remember we were in the car with MIL in the back with Jesse and he put his thumb in his mouth, she said "Get that thumb out of your mouth".. he was 3 months old! I said to her, it is fine, honestly, if it is going to keep him content in the middle of the night and saves me getting up then im happy with it lol. If he was doing it now at this age, then i might do something about it but most of the time they do grow out of it.. DS did.

Thanks everyone, I'm going to keep doing what I'm doing with the pulling out of the thumb and replacing with a dummy. Hopefully it is something she will grow out of.
