Talk to Dermatologist on Skin Problem

A/a.. My 2.5 years old daughter is having few bumps/blisters like acne on her hands(palms and fingers). I just noticed it in the morning. They are not itchy or painful I guess because she didn't scratch them or complaint about them. I have an appointment tomorrow for her with GP, just asking here to make sure if it is anything serious to be concerned about and could it be contagious. Need your kind reviews.

I will attach the picture in comments once approved. Thanks
