Kate - Al's favourite things are cars and dinosaurs. We found a box of dinosaurs at a garage sale and he loves emptying it out and playing with them. Of course, he also loves the computer! And the musical keyboard...and he showed me a little toy at day care yesterday that made animal noises, he thought that was pretty cool.
Oh and he loves peekaboo type books - where he has to lift a flap or whatever and there is something underneath.

ETA: given its summer there - you could go crazy with swimming toys/accessories...etc goggles, swim ring, water wheels, watering cans, sand pit type stuff...

HTH!
