hey there dollyroux
yes there are twin specific classses
i went to 2 of them when i was expecting my twins
the best one was run through my muliple birth club- so practical- best thing i did was join my MBA when i was pg - your local club for your area would be the Eastern Area MBA- they have a website
My multiple birth club run their classes through the northern hossy so your might do the same
also my hospital that i birthed at had a twin specific ante-natal class
i birthed at FPH
definately contact your hossy where you are birthing at and ask
i know that there is a system now that matches you up with a multiple birth club through your hossy and passes info onto you about such things as ante-natal
