Baby movements

Movement patterns can change. Some days, baby more active than other and sometimes, baby positioning also effects how much you can feel the kicks. I never count movements though. My first child was never a super active baby in belly. I think I would get so paranoid if I count.

week 21 is still early to have a regular pattern of movement. week 28 onwards will be more consistent, have to count if bb moves at least 10 times in 2 hours

it is normal .. i am 25 weeks now and no regular pattern yet .. sometimes baby very quiet, somedays he is playing football in there .. so ya .
