I was also going to suggest nick-naming her "
Izzy ". As to
Nanaea 's remark about "baring your teeth in a frightening manor and screaming",however jokingly, isn't the answer. As someone who works with kids, I've learned the best thing you can do is keep saying her name correctly yourself, and eventually he will learn to say it, too. It's just like him trying to learn any other word. But, I still like the name "
Izzy ".
