Biting, yikes. I'm SO afraid of that, my LO has no teeth and he sometimes gives me a chomp, can't imagine with teeth! Does the biting phase last long, my nipples hope not!
My LO likes to:
Flap his little arm like a chicken,
Kick his leg like a frog,
Pop off and smile and then get a serious look on his face like 'Oh....got to get back to eating' and pop back on. We have some great smiling at each other moments when we feed, just melts my heart.
