Eh takde apa yang salah, quite normal actually! A few of us mums felt the same after booster, baby jadi lebih aktif sikit, some say maybe baby react sikit jer to the vaccines or just the mom's body temperature naik. Just stay hydrated and rest properly, yang penting u monitor jer if movements jadi extreme or u feel something off then check with ur doctor aah, but honestly most of the time ni just passing phase je. Keep an eye for the next few hours, if baby still hyper mcm biasa then all good!
