Both are fine to use and they have the same meaning. I cannot say right now a difference between them (except the article). I can only notice here, that english language is not so flexible as romanian, and you cannot use child without "a" article.
Mulțumesc! Yes, I have noticed that there are a lot of things that can be omitted and just implied in Romanian. I guess my only concern at this point is when to determine when words are implied in a sentence or when they can be used.
