45 is too old to have a baby and you’ll never have a brother or sister

[Tiredofwatchingliloandstitchnow]

Dd, 6, said to me a friend at school had asked how old I was and Dd said 45, the girl then said that was too old to have a baby so my Dd would never have a brother or sister.
Apparently they were talking about having a brother or sister when this girl asked this. Dd then said I had a brother and sister (her auntie & uncle obviously) and please could I have a baby brother for her.
We had almost ten years of infertility and losses before having her via ivf, this comment hurt so much, it was hard to hold back tears in front of her. We do in fact have a frozen embryo from my late 30’s so 45 possibly *Isnt too late.
Aibu to feel annoyed about what this girl said to her and to feel sad I likely won’t be able to give my Dd a baby brother?
Anyone else have an only and have they ever asked for siblings? If so, what do you say?

Why haven’t you already tried with your frozen embryo?

@Seagrassbasket It was the plan and then covid came, clinics were shut and then I got long covid…now I feel sad that it may be too old

It's not a case of which is more unusual. If a child did have young parents, they might think it's too old, or if they had older parents be surprised at someone younger being a parent.

Most likely, she's asked her own mum and she told her she's too old.
