I don't think she FULLY understands what is going on. When I told her (I told her by myself) her response was "Oh my gosh mommy! I can't believe it! I'm so happy!" & gave me a huge hug. It was so cute that I wish I had told her in front of other people so they could have seen it.

We had to explain to her a few months ago that my nephew was getting a baby because the baby was in his mom's belly, not mine & that she was getting a baby cousin because she was all gungho about her getting a baby. But, now we have to reverse it. I think once my belly starts getting bigger she will get it a bit more.
