Yes, I am finding the 'no play dates' policy to be very frustrating as well!!!!! I live in Ottawa area and the CCPRN is hosting extra children's events so that caregivers will still have opportunity to socialize in public. It isn't the same but it does mean that I can have a few minutes of adult conversation
Also, with the 'no play date' policy it doesn't mean that you can't get together with Mom's and have play dates. I don't know a whole lot of people but I am certainly looking at seeing if I can meet some Mommy's and tots to have over for play dates.
In the summer it is definitely easier to socialize and meet in public places, but yes, the winter it is very isolating because we are daycare bound often.
To beat the winter isolation, I am currently taking my daycare children to approx 3 - 4 children's events per month, 1 field trip, music lessons every other week, and getting to the park every single day that we can. I can't stand driving the daycare children to and from so many activities but it is the only way to stay sane, lol.
