Rolling over2

彼女は寝返りは割と早く3ヶ月くらいからしていたが元に戻るのにもその倍以上の時間を要した。

She had been rolling over since about 3 months earlier, but it took more than double that time to get back to the original state.

彼女はその時床の上で割と強めに頭を打った。泣くと思ったけど、彼女は驚き最後に笑った。

She then hit her head relatively hard on the floor. I thought she would cry, but she was surprised and laughed at the end.

彼女の思い通りに動けたからか偶然のものか。きっとこういうのが記念日なんだろうな。

Maybe it's a coincidence because she could do what she wanted. I'm sure this is an anniversary.
