Does toddlers shiver for 10 or more secs when they get scared of anything..like fire crackers or loud sounds and lot of people around

A. Yes yes I trembling is very normal with kids during this time because they get scared so they can shave a little bit for five or 10 seconds and that’s very normal for them if you see that happening with every sound then maybe it’s just a normal thing that your child is scared of sound but if it is specifically with something or sometimes then you can consult the doctor
