Baby movements

I'm just curious if this is normal or happening to anyone else. I'm currently 26 weeks today with my first. I started feeling her really early at 17 weeks. And from 19 weeks on every day her kicks have been so strong you could feel and see from the outside any time I laid down.. Like I said it's been daily. But when I hit 25 weeks it's been only every now and then I'll feel a small kick. So it's been a little over a week now that she hasn't been kicking like normal. Is it normal for a baby to go from crazy active to very lazy?
