I've been reading reviews of different books and how to introduce the donor egg aspect with our children. It made me realize I haven't shared some of the fun stories of the girls learning more about this.
I figured that with Nolan coming into our family they would have more questions about babies and I was right. They asked how Nolan got in my tummy and I kept it simple with saying "mommy and daddy went to a doctor who helped put Nolan in my tummy" and that we went to the hospital and the doctor helped us to have Nolan. Nothing I felt was misleading but enough information for a little 4 year old mind to understand. They seemed okay with it and remained fascinated with their baby brother and not necessarily where he came from.
A week or two ago though we had pulled social security cards out of the fire safe for tax season. I found the girls embryo-scope picture. I thought they would find it interesting so I brought it upstairs and showed it to them. They were interested and started asking questions. I told them how babies were made from egg and sperm to become an embryo (like the picture). I also told them I didn't have any eggs so a nice lady gave us some eggs to help us make them. They were fine with this explanation and didn't ask more. Then Seren started asking how the doctor got them into my tummy. She said "did he make you swallow us and we went down into your tummy" (motioning with her hand into her mouth and down her throat into her stomach). Oh wouldn't it be easy if that were the case. I laughed a little and then reintroduced the difference between boys and girls that we've explained since Nolan's arrival. I explained that girls also have a uterus where babies can grow. I explained the doctor put their embryos into my uterus and that's where they grew to become babies and be born. Kendall then piped in and asked "so then the doctor cut your tummy open and we were born?" (with a prying motion to her own tummy). HAHA Not exactly. I told them that some babies were born that way (with a doctor cutting the mommy to get the baby out) but some were born another way. I didn't go into more detail there and they had enough of "the talk" by then and were ready to go play.
Honestly at least the medical aspect makes it more simple to answer questions about how they came to be and came into our family. I'd rather explain that than the other method of having babies at this age HAHA. I'm sure we'll continue to have some interesting discussions about this along the way but for now we're starting on the right foot I hope.
