Wahhh comel nya, 20 weeks and dah aktif gerak2, confirm baby ni pun akan active like kakak/abang dia! A few of my mum friends also had second babies with the same due date as their first anak, and they said the energy level masa pregnant kedua memang lain, pastu bersalin same time macam "eh tunggu, I'm doing this AGAIN!" haha. The movements at 20 weeks definitely vary from baby to baby, so it's totally normal if this one gerak differently from your first; some babies just lebih hyperactive dalam perut. Excited for you lah mama, double celebration date!
