She keeps asking

My 3.5 year old ask me a while back how baby was going to come out of my belly, and I told her doctor will take her out at the hospital and give her to us. She then followed up with "is she going to cut ur tummy to come out, cause that's gonna hurt," Im not having a csection ( at least not planned ) and I figured she was more worried about mommy being hurt and I ask her, r u afraid I'm going to be hurt? She said yes and I explained to her that I will be ok. We left it at that. Several days later she mentioned that baby will come out of mommy belly but it's not going to hurt mommy, and it wasn't a question more like she said it in passing so I let it go. Today when we said goodnight she kissed me then my belly and says, but mommy baby is going to be here soon and will cut ur tummy to come out right? Because it was bedtime I didn't think it was appropriate time to tell her truth, and I'm still debating if a 3.5yrs old needs to know how a baby is born (my hubby doesn't think it's necessarily to let her know) but I feel like she keeps asking because she's not satisfied with the answer she got but yet i don't want to traumatized her. Thought/advices how to handle this keeping her age in mind?

How cute, I would say something like; "Well it sure didn't hurt when you arrived filling mommy's world with joy so in sure (baby's name) arrival wont hurt either."

I dont think you should lie to your kids   My mom told me everything 'important' from a very young age if I asked directly. I still remember I was 4 and asked if I came from her belly. She kindly explained that I came from someone else's and showed me pictures of the other girl. I think it would hurt her more if she thought someone was gonna cut your belly. Im going to be honest with my kids too if they ask, my mom was an amazing person and I'd like to be like her   Just tell her the truth it will be fine  

They're never too young to be told the truth  

Find a word you are comfortable using for vagina, and explain it to her that way. If she is worried about you getting cut open, and she thinks that is how it is going to happen then she may get really upset when the time comes. Let her know that is how she came into the world and that the new baby will not hurt you and everything will be alright.
I would prepare however for her to possibly inform other people that you will be having the baby from your *insert term here*.

My son knows that babies come out through the vagina. He also knows it hurts and although it worried him that he hurt me while coming out, I told him mommy was okay and that it's just how life is. I'm not going to lie to him when I watch tv shows that show women with their legs open and a baby coming out....that's actually how the questions came up lol.

Ehhh it's a touchy subject. I have a 6 y/o son and 4 y/o twin girls and they of course have been asking since my belly started to grow bigger and a lot more lately (I'm due in 3 days) "How is baby Savannah gonna get out of your tummy?" Well I do have a scar from my c section with the twins so I showed all 3 of them and told them the Dr. was gonna open it up and pull her out. Well of course they went on with "Isn't that gonna hurt you mommy, are you gonna cry?" But I just told them they were going to give me medicine to make me feel all better! They seemed pretty satisfied with that, but still ask me sometimes randomly how and when shes gonna be here! Contrary to what I've told them I'm actually trying for a VBAC and I'm opting for no epidural but I'll save that conversation for later on down the road. I'm personally just not ready for that yet   they are still babies in my eyes.

Alphonse asked me all the same things when I was pregnant with lilly. I told him she comes outta mummys belly and he asked the same about me being cut open, I said no mummy will push her out. Then just after I had her (he was staying at his gmas) ha came and told me that I pushed her out with my muscles, so she must had explained it to him abit, but he samed to be happy with that answer. Maybe try telling her something like that?
