Hot or Out?

Recently Olivia has been saying either, "Hot" or "Out." We think it sounds more like "Hot," and if we say it she usually repeats it right back. We are pretty sure that she has been mimicking Ella at the sitter's because Ella always stands by the door and says, "out" for outside. Either way Olivia is trying to say something and there is a definite "t" sound!

I am going with "hot" and I made sure to mark it the baby book:)
