Vent - Unhelpful People

Posh
My mom wanted to stop by for a quick visit to see the baby. I made sure the baby was fed and happy by the time she got to the house. I handed her the baby and then went outside to spend time with my 2 year old. Within 10 minutes I had to come back inside because the baby was screaming. Her diaper was full, so I changed her and calmed her down. My mom then proceeded to ask if I was tired, um yes, I have a newborn. She then responded with "yeah, well you look like it". Well damn. Maybe it's my lack of sleep or my hormones, but that comment was uncalled for. So she came over, upset my newborn, got my 2 year old riled up, insulted me and then left. What was the point of this visit??? Vent over.
