We have created a monster!!

So I am VERY stubborn! Guess what? So is my husband! Why did we think it was ok to have an equally as stubborn son?!? Ok we didnt really have a choice (and of course we wouldnt want tp trade him for anything/one!) but man he is sooooo stubborn and the worst thing is that its sooooooo cute! He has suddenly learned this really annoying and cute high pitch squeal. Im not sure why, but it started about 2 weeks ago and he seems to do it when he is annoyed or wants us to do something different (ie hold him a certain way, stop changing him, give him his toy etc!). We have been laughing at it because it caught us by surprise and I love hearing the change in his "language" but I think we are just making it worse. He now knows that we think its funny and will do it when he is happy too. I asked my mom how she dealt with me at this age when I became so demanding and she said she just ignored the behavior. I tried that and I got screamed at more! We seriously have our hands full with this one!
