Before I begin, let me just say that nothing explicitly bad happens to any children in this dream, so read on.
I was on a trip with my husband and two kids, plus my in-laws. All of a sudden the in-laws start talking about "him" and it dawned on me that I had a third, younger child and I had no idea where he was or how he got there. They made a phone call to the folks with whom he was staying--some random great-aunt or something. I asked how he was doing and they gave me details and said, "Well, it's Day 6, so he's getting REAL comfortable." (I don't think I have ever even spent 6 days away from my kids IRL.) It was as if I had blacked out his entire existence and I was racking my brain trying to remember things like his birthday, name, when and if I spent any time with him at all, and if not, where he spent his days. I knew my real DS was usually with me or at preschool and that DD was at elem school, but I couldn't remember anything about my youngest. It was so depressing! Anyway. Just confirmation that I am probably maxed out at 2. Have a good weekend!
