Totally normal. I didn't let a sitter (non family) watch my kids till they were verbal. We had a bad experience and I never would have known if my child could not speak. We might be that one in a million who that occurs to but it took me forever to trust anyone. Now I have to personal know the mom of the sitter we use really well. Trust your gut. Ask someone on your local triplet group for a recommendation if you need a starting point.
