I'll try to be brief! All my life I was never 100% sure I'd have children. Had a good career, met DH relatively late in life. At that point I would have been happy with 1 DC, who arrived promptly. We decided to have another one quite soon, I fell pregnant quickly again. And yes - you guessed it from my username - it's twins. It'll be hard and it was a shock but I'm so happy, we both love being parents and DC is great fun.
DSis is a good few years younger than me. Was always super maternal, works with children, always said she wanted lots of her own. She's been settled with her now DH for ages. Guess what? They can't have children. It's male factor, they've just started IVF.
I'm heartbroken for her. When she told me they'd been TTC for years (I suspected as such but never asked obvs.), I knew I was expecting DTs. My heart sank. I told her in due course. She wants to be involved in my DCs lives. I send photos, we talk about them, we visit. But I can't shake this sadness, she must have to try so hard all the time. I try to talk about other stuff, I don't make a point of being pregnant, but it's hard when you're having twins and massive.
I don't know why I'm writing this. Is there anything I can do to make things easier for her? And also, realistically, what are her chances with IVF? Transfer day next week, I think about it constantly, I don't know how she's managing. I wish we could swap places sometimes 
Thanks for listening.
