Would you find this offensive?

I had a baby in April 2 years ago. I told my in laws that I had a feeling baby would be born early, around my SO’s birthday (due date was in late May). My SO’s aunt told me that she thinks the real reason I wanted baby born in April was so that when my husband bought me anything with the baby’s birth stone on it, it’d be more expensive than if he was born in May. I felt really awkward and didn’t say anything. I didn’t care about the birthstones, I don’t even know what my own birthstone is lol. It was just mom intuition and, obviously, it was right. When she said it it just made me feel like she was calling me a gold digger. My SO never even ended up getting me anything with baby’s birth stone and said he had no plans to so idk where she even got the idea from

Well I’m pregnant and, again, due in April. Since last baby was so early and was small at birth, my OB said they want to do what they can to keep baby in for as long as baby will stay. I was telling my in laws about my appointment and this same woman starts saying that the “real reason” I want baby to stay in is so that I can get another more expensive birth stone and have two of them. I feel like it’s even more insensitive to say this time because she knows how rough of a two weeks we had when baby was in the NICU and couldn’t even fit premie clothes.

I think she thinks she’s being funny, but it’s actually just really uncomfortable
