Hi and welcome to YT!
I dont know about parks in CT but you might want to ask about it in Regional forum. You will see the button on the bottom of yorkietalk banner.
Also I think there are couple of meetup groups for yorkies on meetup.com Here is the link to the meetup that I joined not that long ago.
Yorkie Nation (New York, NY) - Meetup.com
It seems as a nice group just didnt have a chance to go to the meetups yet but I recieved a couple of fun events. Hope it helps.
P.S. Your baby is adorable!
