子どもが夜中に咳こみながら嘔吐
My child threw up with coughing at night.
熱は微熱程度だし、本人は元気だけど、悪化しないよう幼稚園は休ませることに
Although my child has a slight fever, he is so fine.
However so fine, I keep him home so that he won't get worse.
最近イベント続きで疲れたまっちゃったかな～
He might have been exhausted lately, because we had many events.
#最後の「疲れがたまる」とか、調べながらの英訳なので、表現がちょっと自信ないな～
