Another first for Amelia is the dreaded boob lip. This new trick started a few weeks ago and she pulls it out any time she's not getting her way. It's proceeded by stomping of her feet and a few shouts (no joke). I didn't realize that tantrums could start so young. How do you teach a 10 week old not to throw a tantrum? I thought only undisciplined children behaved this way, but I'm learning that they can just be born this way. I snapped the end of one of her boob lips here just before the feet and wails started.
