This is an interesting discussion. My DD age 3 regularly chats about her birth and "monsters" being there when she was born. Well, I had a c-section so everyone there was fully gowned and masked, so who knows? She also said she was up in the sky floating before she was born. She has spoke about a couple other incidents during her first year with such certainty, I wonder if it's actually a memory. She has a very vivid imagination and has invented a place called rainbow land and a fictional sister that doesn't live with us, so sometimes it's hard to know when she's imagining and when's she's remembering.
