Hi and Welcome.
I'm in Edison so I can't recommend any pre-k schools close to you since the ones I use are a bit out of the way. However, there are many mommy and me classes offered at many gymnastics places, dance schools, THE LITTLE GYM, etc. I'm currently looking into a class for me and my 3 yr. old at EASTERN GYMNASTICS in Cranford which is close to you. They have a website which may help you out and it's a nice facility. My older children (ages 8 and 10) also take gymnastic classes there as well. Friendly staff too. I think THE LITTLE GYM is located in Westfield if I'm not mistaken and you might have luck with that as well. Good Luck.
