・always watching over you
・keep an eye on someone

我一直守護著你是always watching over you/keep an eye on someone來表達。

watch over someone是"細心看著，照顧著"
keep an eye on someone"意思是「仔細觀察，眼睛不離開某人或某物」，"這是一個慣用語。

Mom is always watching over you guys.
『媽媽一直在守護著你們。』

Let's just wait and see what my kids will do next time.
『讓我們拭目以待，看看我的孩子們會做什麼。』
