I am so bummed for my son and he doesn't even have a clue. He has developed a new interest. I bought his dad a NASA space shuttle simulator and he really likes watching/playing it, asked me for a space shuttle toy, searched ipod touch for "space shuttle free" apps (I was impressed!) etc. I was so proud of myself for actually finding a space shuttle little toy at the mall for him and when I brought it home he says...what about the boosters and the external tank?! Duh, how could I not know Anyway, the reason I am so bummed, is that we are going to Disney the first week of February and he has always been ambivalent about the rides, the crowds etc. so I was really excited that we would be there when they were going to launch the space shuttle. I just read that its been pushed back though. I hadn't told him about it (we know better than to do that!! Do you all get totally "into" your kids interests? I jump into them and use them for opportunities for language and interaction, and sometimes I end up asking myself...is this obsession or mine?! KWIM?
