As responsible parents, we kept all loose blankets and other 'hazards' out of our son's bed when he was a baby. As he got a little older, we allowed him to take a single stuffed animal to bed, hoping to cultivate it as a lovey. Once he could express his preferences, however, he began sleeping with wooden trains from his Thomas the Tank Engine set. That's trains, plural. For a long time, eight of them, and he would immediately notice if one went missing. Recently, he has asked for different trains and, occasionally, different toys altogether. But always some sort of vehicle. For a recent nap, a bulldozer and a backhoe, two significantly larger toys than usual--but as he's been feeling a little down, how could I say no.
Most of the time, I just wonder how comfortable it could be to sleep with plastic and wooden toys. He tosses and turns a lot in his sleep, and so he regularly ends up on top of them. But he doesn't seem to mind, so I figure, "Why not?" Of course, on those occasions he ends up in our bed, I end up minding, as the trains come with him. And I know from experience that James leaves a nasty bruise in the middle of one's back.
