I hate it when people get all judge-y without knowing what happened.
Every time I see someone with a toddler (or even younger!) that's all bruised up, my instant thought is either "someone's learning to walk!" or "someone's not learnt how to stop running!" lmao.
If the child looks happy and well cared for, my assumption is not that the parent is beating them but that the child is simply doing what kids do. And getting the war wounds to prove it *chuckle*.
