Sweet M* Baby

I knew this day would come, but I didn't realize how soon.

We are leaving later this summer for Disneyworld and we will be flying so I have been talking to Sweet M* A LOT about airplane rides and where we are going, the hotel, etc... So, last week I decided to get an older photo album out with pictures of us there to show Sweet M*. He loved looking through all of the pictures and then he asked about the baby in the pictures. I explained that the baby was Belle when she was little. He didn't get it though. He would point to another picture of baby Belle and ask if it was baby M*. When I explained that those pictures were all baby Belle he started looking through all of the albums for baby M*. I explained that M* didn't live with mommy (me) when he was a baby. And, we went over his past... that he was born in Ethiopia. He had an Ama and an Aba (mom and dad in Sidamese) etc... But, he said "No, Aba/ Ama... mommy coming." And, then he continued looking for baby M*. I didn't know what to do so I jumped online real quick and showed him a picture of a newborn baby with brown skin. He LOVED it and proudly showed baby M* to his sister and I. But, I felt so bad.

I try to prepare for these types of moments, but that day last week I realized I can't always be a step ahead. Sometimes I'm going to have to think on my feet and I am not always going to do the right thing, or say the right thing at the right time. My question is what would you have done???
