proper way to answer children about their birth   

Children are curious by nature. Do not shush them away, try answering them as per their age. To your 2-3 years old child, you can say that babies come from the hospital. They are just curious. Focus on the love and they don’t have to be told about sex. To your 3-4 years old child, you can show them seeds in the soil and how they grow, and tell them that similarly, a baby grows inside a mother's womb. Tell them you love them and they do not need to be told about sex yet. To your 5-7 years old child, you can show them some picture books from the library of how a baby grows in the mother’s womb. It might happen that kids will ask more questions after looking at the pictures. Take this as an opportunity and explain to them about their genital parts if they raise questions regarding that. Do not tell them about sex yet. Normalise loving and accepting their body.
