Hi there! I can't help much with daycares (we used an in-home, and now I SAH)...we go to Cary Peds, and have had a great experience there for 6 years.
As far as playdates - it's been hard for me to really partake very much because of the difference in my kids' ages, preschool, etc. There are definitely groups out there - in addition to the PP suggestions, I would say maybe check out Triangle Mommies. They have a very active calendar from the looks of things.
Thanks ladies! I have already requested to join two of the meet-up groups and I am looking forward to meeting other people at the park. I will check out those two pediatricians as well.
Thanks for the warm welcome
