moms of 2 or more dc- mommy&me or separation classes

i have 20 monnth old twin boys and 3 month old dd i want to enroll them in some kind of class but if its a mommy and me i dont know that i can keep all 3 tame so to speak
Does anyone know of any recommendations in the suffiolk area im in Port Jeff Sta.
I was thinkin maybe a music and me class??? can my boys run around in that class?
i think the library is a little too quiet and calm and to be honest i dont know that i can control them fully unless there in an enclosed room.
TIA
any help is appreciatd--- thanks
