Hi T.! I live in Old Bethpage and have two sons who are 3 1/2 and 1 1/2 years old. There are many opportunities for people with young children in our area to take classes and meet other parents. I would recommend looking into classes at the following places: My Gym, Gymboree, Mid Island Y JCC, The POB public library and Once Upon a Treetop. To be honest, your daughter is not likely to get too much from classes at this point (since she is so young), but it is a nice way for you to meet people. You may also want to go to the website Minglingmoms.com. You did mention that you were on maternity leave so you may want to look into things on weekends so that you can continue with them when/if you go back to work. I have always done classes with my boys on weekends and have met a number of nice people at these classes. Best of luck and congratulations on your new baby!
