DS is 3.5 and he's currently into playmobil anything and imaginext ( especially the bAtman line) anything. If he's not playing with those, it's because he's outside.

@Bao: I think they're a good toy to transition out of little people, if that makes sense. They're smaller and have little parts, which he's loving. Right now we just have the ambulance and the camper van, but he can play with them for hours. They also seem very well made. He seems to have graduated out of little people here recently. They don't hold as much interest because they don't move and don't pop apart. The smaller pieces are a pain, but with just the 2 vehicles, I've been making him be more responsible with them, and it hasn't been awful.

Balls and books are pretty much all he plays with! Obsessed with any ball. He is 18 months old.
