Nope, OP, you sound at normal range and paying legally is the right thing to do. You dodged a bullet with that one. No worries. If you're not getting the candidates you want at that range, try bumping up another dollar or two. It won't end up being that much for you individually, but could make the job a lot more attractive at $23/hour than $21/hour. It is two young infants too, so you'll want to be sure you're getting someone very qualified and trustworthy.
