I have a May babe too, and exactly what the others said, though there's plenty of cool kids stuff that's doesn't have to be a wondersuit and is still warm if you don't like them. Me I'm a practical (read lazy) mum. They were just easier. Darcy was 6months old before she became unwell really. Makes toilet training at 18months easier because now it's warm enough for no pants....and learning to walk - warm enough for no shoes around that age too.....
