You do not generally hyphenate the word stepchild, because it is not a hyphenated word. If the question is where to hyphenate stepchild if you have to break it across two lines, it is not difficult to determine this, because the two syllables are actually separate words: step and child. If you have to hyphenate the word to break it, you would put step- on one line and child on the next. If the word is all on one line, you do not hyphenate it.
No. This phrasal verb is made up of two separate words.
its used to hyphenate words like half-empty

You hyphenate words to create new compound words that are uncommon. - During the first years or decades after the creation of a word, the new word is spelled with a hyphen, which tends to disappear after a certain amount of time for ex.: to co-operate, to cooperate. The first phase of the process is simply the creation of a group (no one), then we get a hyphen ("no-one" as it is spelled nowadays by the British) (or "good-looking), and the last stage is the amalgamation: "always", "welcome". - These new words are usually compound words. Hyphenating words is also not that formulaic. There are many more reasons to hyphenate words -- numbers for example "twenty-three," last names such as "Jimenez-Cabrera," you also hyphenate words that have become linked in usage such as "mother-in-law."
Spell it as you have done in your question but hyphenate the words so that you have self-esteem
