I read my children a story called kangaroo pouch or something. It's about a kangaroo who wants to be a mummy but her pouch doesn't work so her friend says she'll look after the woman's Joey in her pouch until he's ready to come and meet his mummy.
But in all honesty they didn't care. The littlest one was too small and the other two just took it as the new normal. Kids are adaptive like that!
I have a lovely necklace from baby 1 to say thanks and when my eldest (now 9) commented on it last week I said "Anne and John got it for me" (the parents - not their real names!) and he actually looked at me quizzically and said "why?"...
I was like, ffs dude, I had A BABY for them!!! It's kind of a big deal.
I told some people about the surrogacy when pg but generally only those who I knew I'd see afterwards. I didn't want them to think I'd lost the baby or anything like that.
Mostly I just smiled and nodded when people would say to me "you're gonna have your hands full" when they clocked the bump and my three. Too much to explain, too little time.
I am always surprised at when I do mention it oftentimes people come back with tales of their conceiving woes. It really is more common than we think, infertility struggles.
