Changes in movement

Usually right when I wake up baby girl isn’t too far behind kicking away. This morning she was slow to wake up and only a few kicks here and there. I ate some fruit and laid down in bed and she kinda perked up but not much. I was starting to get worried. Randomly later in the evening around 5 she started going crazy! Kicking and rolling and squirming around for a good hour straight. Since then she’s been back to her normal self. I don’t know if she was just sleeping in this morning or what, but I was definitely starting to get nervous.
