Pops, we don't get measured here, the midwife just has a really good feel around your stomach, shows you where the baby is and tells you if it seems about right!
Babydreaming, they look fine to me. We had a few different brands last time and they all have different style fastenings. We developed a strong preference for the Grobag brand, but I think you wouldn't know until you tried different ones.
I've actually got three slings now! I thought I didn't know where the two I had last time were, so got an Ergo from a friend. But now I've found the others! One is a beco Gemini, which I used loads. It's very comfortable, and I could breastfeed without taking it off. The other is a Baby Bjorn, which I didn't like but DH loved.
I've just packed a hospital bag! Am I the first?! I left it loads later than this last time, but I just have a feeling I might need it early. Partly because the baby is growing slowly and I think might turn out to have IUGR. But partly because I've had two friends with the same due date as me and neither had December babies! One was November and the other was October, which is next month!!
