Are old people like this? After grandpa hugged the baby, he would touch my chest and watch me breast-feed the baby every time. It's disgusting. What should I do?

Then why are you holding his baby? It feels like you did it on purpose! Old prudes are people like them! Don't tell others, who knows what they will think behind their backs, it's okay to be enlightened, and you will be blamed for not understanding! Besides, such behavior is very hidden, and it is difficult for others to find it. You have to find a way to solve it yourself! Nurse! Go to your room! Hey! Give the child to grandma. Wait! Try to avoid physical contact!
