@bon92, at about 20 weeks is easier still not 100% but they still have so much room and that they can be moving and we dont always feel it... then i think its around 26/28w that kick counting becomes easier. but if you have concerns go get checked over or let them know
Not a lot at 16 for me but now at 17 I feel bubs every time I lay down and sometimes when I'm sitting :)
