I worried and wondered about this too!
Funny story?
My twins are boy/girl, not to mention a pound and a half different at birth, so it shouldn't have been that big of a deal....
As we were leaving the hospital, I got out all the fun pink stuff (remember, I have three older boys and this is my first and only girl) and went to change Lynndi's diaper and get her going home outfit on. Got to her crib-tub thing (those hospital cribs with wheels), and went to change her. Opened her diaper and about had a kiniption --- I KNOW I had a girl! This baby was not a girl. I went to wondering if I was having a bad dream, a nightmare. I made myself search to see if it was a dream. I went to wondering if I'd imagined one was a girl and I was honestly crazy and they were both boys....
I was honestly, truly having a breakdown - freaking out in the truest sense of the word. But, it didn't last long. Maybe 10 seconds max....
I realized, the nurses just put the babies in the wrong tubs.
(Much of my little mini-breakdown just had to do with the whole my-first-and-only-girl thing. I'd been praying for a girl for 12 years by then, and maybe I just was looking in all the dark places to make SURE I really finally had her. LOL)
Maybe that story sounded freakier here than it was. Within minutes I was laughing at myself -- too funny!
When the babies were little, I'd stick a white diaper on them both and when hubby got home we'd have them in different rooms and ask him - POP QUIZ!! Which baby is this??
Took him about 3 days before he was 100% certain all the time, but even he got where he could tell.
And I must add -- I think the whole painting the toenails different colors is a FANTASTIC idea!!! Love it!
