We started @ 9 months. eased into it - I went with him for a few hours for the first couple of days. He's now 15months and there's a boy he plays with all the time, and another boy he steals toys off all the time ... He loves it, big smile when we drive there in the morning.

For us, its great, but that's because we found a centre that aligned with our values and is smaller (council-run) and he's thriving there.
