I find if I haven't felt bubs for a bit I have a glass of cold water and stop moving myself. Sit down and just concentrate on bubs for a bit. Soon after I get a kick or a shuffle.
Sometimes I don't feel her for hours especially through my busy times of day. I think I just rock her off to sleep lol.
It can be hours between movements for me. Then I get them all night when I want to be still LOL!
