When I was pg with Isabelle, from about 30 weeks until she was born, she would kick me non-stop all day from the minute I woke up, until the minute I went to bed!!! Pretty good effort - she has turned out to be a pretty active bub too, not sure if it is related but completely normal! When she had bouts of stillness for 15 mins or more during the day I wondered if everything was ok! She obviously just needed a rest!
HtH! Good luck!
