What to recite to save oneself from "nazar"

In Islam we know that there is something known as "nazar" or "the evil eye" and what are its negative effects and harms etc.

We would like to know, is there also such a thing in Islam as "sweet nazar" or "good nazar"?

For example, when a father or mother looks at his/her child with a look of pure love and forgets to say "Maashaa Allah", then can this glance of love have a negative effect on the child? Since there is no question of jealously for one's own child, can there still be negative effects in an innocent look out of pure love?

If so, does this principle apply to everything that is dear to you?

For example, if you look at your own car or house with a look of amazement without saying "Maa shaa Allah" then can this have a negative effect on it even though there's no question of jealousy for your own belongings.
