G/C
My little one was born I'm September 2010, right at the beginning of September. She lived in lovely hand knitted cardigans and blankets for the first few weeks when we were out and about. The weather was still very warm, so I though it was best to put layers on her.
Our first snowsuit was size 3-6 months, but she was in it by about early- mid October. It was to big at the start, but they honestly grow so quickly, that after about 2 weeks it fitted perfectly!
Hope that helps! Xxx
