Please help wise women of Mumsnet. DS had a lesson on puberty today and has been asking how exactly the sperm and egg get together. His teacher said he wasn't prepared to answer and if they want to know they should ask parents. Does anyone know of good books/videos to explain this difficult topic in an age appropriate fashion to a 9 year old? I should know this but though we had some time yet.
AIBU to ask for guidance on this.
