- I wonder if its because school has become more difficult but my daughter has been complaining that she wants more time to play at school.
school has become more difficult = 勉強が難しくなってきた;学校が少し大変になってきた
My daughter has been grumbling that she wants more time to play, probably because her studies have been a bit tough lately.
「最近は勉強が大変なのか、娘はもっと遊ぶ時間が欲しいってぼやいています」という状況は、
My daughter has been grumbling that she wants more time to play, probably because her studies have been a bit tough lately.

wants more time to play は「もっと遊ぶ時間が欲しい」という娘さんの気持ちを直接的に伝えています。
lately は「最近」という意味です。
