M.P.
My son goes to The Children's Center on Craft Ave. behind Magee. It's affiliated with Magee and is a sister daycare to The Carriage House in Squirrel Hill. It's a great location for me, as I work at Pitt. The Pitt daycare is great, but I've been on the waiting list since before he was born (2.5 years total now), and they still expect that a spot won't open up for him for at least another six months. The Children's Center is good but expensive. It was the only place whose waiting list we were on that came through on time.
I'm not from Pittsburgh, either, so I know how difficult it is to find places. I hope you've had some success.
