Since 2005 Supreme Court decisions found juvenile executions unconstitutional as "cruel and unusual punishment"[50][51][52] and that mandatory sentences of life without the possibility of parole are unconstitutional for juvenile offenders.

So the US already can't execute or imprison children. So that's not the reason for not signing it.

Note that the US can still given juvenile offenders life sentences, it just cannot be a mandatory punishment for a crime.
