Not an expert on cs or twins, but my two pregnacies were totally different. DS1, kicked and turned every second of every day, needless to say he is a handful and cannot sit still. DS2 rarely kicked and never turned, he is the most placid baby, and loves to sleep, at 9 months still has 4 sleeps a day! So I am sure every pregnancy and baby is different, but I know it's hard not to stress! I am sure with twins, you'd have felt every single twitch!
