A question, my husband took my 20 mth old to McDonalds as a treat and my son was playing in the playground, and another child pushed my son not once but three times, the mother of the other child watched as it happened. My husband knelt down and explained it wasn’t nice to push another child. The child’s mother got upset at my husband saying he shouldn’t discipline her kid and pushing another child is part of playing. Husband and my son came home upset. What would other parents do in a situation like this?
