I think people might get you mixed up... Especially in that phase when you're doing new baby things and meeting other people with new babies. "Oh, I met a lovely woman at the baby massage class... What was her name, now? She was Zoe and the baby was Chloe. No, other way round. No, I can't remember." I met mum and baby called Martha and Matilda - not even that similar, and I still can't for the life of me remember which is which. I had to stop talking to her in the end because it got embarrassing.
Having said that, Zoe's lovely!
