The warmness from people's hands probably comforts the baby so they stop wiggling lol at least that's what I tell my husband when she doesn't move for him
My son does the same thing. He will only kick for hisbdad and I. When everyone else tries to feel he suddenly stops. I have to have my hand on my stomach as well as whoever is trying to feel him in order for him to kick for them.
My baby girl does it too.
Her mother is far from shy i wonder were she get Its from
I don't know but my baby girl does the same thing!!!!
