Was my mom being insensitive

My 15 year old daughter went through an ectopic pregnancy and lost a fallopian tube. She's been really depressed about it. The father of the baby was a friend of hers named Wyatt. They lost their virginity to each other. He's honestly a really sweet kid. He stays to himself but when he found out my daughter was pregnant he was ready to quit school to go work on his uncle's farm so they can raise the baby. Wasn't gonna let him do that but I like a effort. He brought her snacks and his favorite books for her to read after the ectopic pregnancy. I allow him to come over as long as they stay in the living room because I know they need to grieve together. My mom came over to check on her. However my mom immediately starts telling her how AMAZING this is that she had an ectopic pregnancy and now she can focus on being a team and not having babies with losers. That was mean because Wyatt isn't a loser and even though he's so young, was there for her. My daughter started crying saying she missed the baby but my mom told her she's crying over nothing and she can always have more children. I told my mom she can feel how she wants and it was her baby. My mom said it would have been an ugly baby and started talking about Wyatt's looks. My daughter and Wyatt are friends so why would my mom think making fun of him would make her feel better. My mom said "Now you don't have to worry about having a baby with a lazy eye!" My daughter yelled at my mom to leave her alone and went outside. I know my mom thought she was helping but I feel she was being so insensitive!

Edit: I am in no way defending mother! I agree she was being insensitive but SHE doesn't see it that way. She sees it as her just helping.
