squeals & shrieks

i remember talking to troy's sister, heather, on christmas. her son, nathan, is about a month older than caleb. she asked troy if caleb was "shrieking" yet. troy said something about him not actually crying much. she explained that it was not upset shrieking, just shrieking. i sort of shrugged and troy said he wasn't sure if caleb was or not yet. what she could have said was, "oh, you'll know when he starts!!" caleb is going nuts with it! it's like the blowing raspberries (which he hardly does at all anymore)... he wakes up squealing and falls asleep mid-shriek. so crazy!
