My daughter is almost four months old. Few weeks ago she discovered and started having a lot of fun with her little hands: she keeps putting them in her mouth, she loves playing with the toys, etc.
However, recently we have noticed that she also sucks a lot on her fists. Especially from 3-4 hours before her bed time, she will start getting anxious and placing the fist in her mouth.
I did read some articles about the pain they may start having by this time, since teeth are starting to develop and this hurts them. However, and if this is the case, I wonder how can sucking their fist soothe them.
Is there any other possible explanation? Could it have to be with stomach ache?
