My kids have gone to Discovery Parent-Child Preschool for 4 yrs now and we love it. If you are looking for a place to meet people, a co-op preschool is the way to go. You can't beat knowing the kids in their class and the parents. You build a whole community of support and meet life-long friends because they have children the same age as you. Discovery has classes for 2yrs old up to pre-kinder. My kids love it. Here's the website if you want to check it out (or you can email me if you have any questions).
It's located off Leigh & Camden (Cambrian area). The playground is awesome, and the teachers are wonderful and warm.
