my dad made ours, but we have been using it since DD was about 18 months as well
we use ours several times every day. i love that DD can watch me make her food, and help with little things (stirring is her favorite!) without falling off a chair
it's so great. my dad ended up making another one for their house.
ETA: one thing we've had to be very careful about is leaving anything dangerous on the counter. DD can push it around, so we keep knives and anything that could be dangerous in a tot locked drawer.
