How much does your 4 year old know? I'm not being hysterical, I'm genuinely intrigued!
😂
Sorry, my then 4 yo is now my 16 yo DD!
I had 3 DC in 4 years so she saw me pregnant when she was 2, then 4, so lots of opportunities for conversions. She was particularly interested - my 2 DS, less so.
In terms of sex itself, I remember her asking specifically how the sperm met the egg / how Daddy made a baby with Mammy etc. So told her that what sex was - penis / vagina etc & that was fine.
I'm sure she didn't really take it in, but without sounding pious, I really always told them factual information & then built on it.
I remember with my middle DS while he understood periods & why women have them very well, I'd obviously missed crucial information because I think he asked at about 11 when he would get his!
Both of my DS (now 12 & 14) have had very frank conversations with me, say about erections, wet dreams, some of the colloquial terms they hear. (Single parent so they don't have their dad to ask) Sometimes I do struggle with exactly how I want to approach a particular topic or how comfortable I feel about a detailed sex question but I usually answer and we laugh a bit if it all feels ridiculous.
