selalu dlm berapa week yg kita akan dpt rasa movement baby dlm perut?

First born sy dulu around 16w dah rasa tapi masa tu since first time rasa mcm eh baby ke. 18w baru rasa tu pun kadang rasa kadang tak. 20w baru rasa baby gerak slalu. Now 2nd pregnancy around 16w dah boleh rasa kalau duduk or baring dlm position tertentu
