I don't remember with DD2 but after 16wks I think and then didn't stop.... Although that was actual kicks.
DD1 was just before 20 weeks I think but hardly any kicks at all.
This one I swear I can feel something but the kid probably only grew legs lol, it's a definate squirm in the one spot, it will be interesting if this feeling gets stronger as bub grows... So I was thinking maybe "they" are right you feel it earlier when you know what you are feeling
