Addy has a red elephant bath toy that she calls "Emmay." I usually pretend that's what she's named it (as opposed to being her word for "elephant") and she talks about it a lot at bath time. Over the weekend I was drinking some red juice and Addy pointed at my cup and said "Emmay" because the juice is pretty much the exact same shade of scary red that the bath toy is. So now I wonder if it's actually her word for "red" and has nothing to do with pachyderms.
