Why ???

My 20 month old keeps touching her head and says “ow”.

it’s at random times.

how can i tell if she has a headache or she’s just doing it to do it?

it’s been for like a week that i’ve noticed it,

any other babies do this?

i also think that if she had a legit headache she would also be in pain and a lot more fussy?

help? super stressed about it and over thinking
