I avoid confusing phrases once I've learned that the phrases confuse the children. So for this child, I would have "put" and I would have "trash". And as I pointed to something or handed them something I would either say "put" or "trash". Clearly, the word "away" is presenting a challenge to them that is making this more difficult than it needs to be at this time in their life. Later on we can work on multi word phrases, maybe closer to 1 1/2 or two. Right now, one word.
