My son is doing an airplane every 5 second from the end of July to around September, 

an airplane is that babies lie on their stomach while hands and legs are hanging in the air. 

I worked hard every day to work my muscles, so I think babies are  really amazing and think human beings is mysterious. 

I want to give him a gold medal to him practicing to move his body so desperately.

息子が７月末から９月辺りまでずっと飛行機のポーズをやっていました。 

毎日毎日頑張って筋トレしていたので、あかちゃんってほんと凄い、人間て不思議と思います。

こんなに必死に体を動かす練習している彼に金メダルをあげたい。
