Can I put my 14 month old front facing?

Miranda

My son is 31 lbs and 32 inches tall. He is in the Nuna Rava car seat and just doesn't seem to fit well in it. His knees are bent and he seems uncomfortable rear facing. Not to mention he hates riding in the car. I know its recommended to keep children rear facing until 2 years old or until they meet ther height /weight requirements of the car seat (which he does for weight, but I don't see the height requirement)

Thoughts?????
