毎 vs ごとに

Hello!
I'm trying to figure out the difference between mai and gotoni.

I understand both mean every, both can be use with a noun. But would it mean the same?

毎日
日ごとに

Don't both essentially mean "every day"?

毎日仕事に行っている。
赤ちゃんは日ごとに大きくなっている。

Both of these examples means "every day". But I don't think you could say 日ごとに仕事に行っている。Seems weird to me. Grammatically it's correct though, right?

I also understand ごとに can be used after verbs while 毎 cannot such as ラーメンを食べるごとにもっと太っている。
