what do people think of gymbaroo ?

took ds(big) to kindergym years ago as preschooler and then it was $5-6 session - OMG now it is $170 for 10 week term
or $60 to try 3 weeks

then we had 8 -10 in a class

just way too expensive and I would need to take another carer I believe anyway for 2 babies

has anyone seen a routine - home made I could do at home have not had much luck googling

open to suggestions /

I have a small plastic slide / swings / I can make our own low rise balance beam on grass /fit ball

what else could we do ?
