While driving home yesterday my nearly 3 yo asked how a baby gets in mama's belly. I was completely at a loss of what to tell her, and just said through her vagina...her girl parts. She pushed for more details but then my 10 month old started crying and she was distracted by that. She knows the correct terms for male and female sex organs, and I want to be honest with her. However, I'm not sure how much information is too much. I want to be ready when this comes up again....age-appropriate suggestions please!!!
