Jeremiah likes to purse up his lips like that when he is not happy. But instead of getting the standard response he is expecting (Oooohhhh, what's wrong baby?), we find his expression so darn cute and funny and we start laughing at him.
THAT pisses him even further and his face gets more annoyed and he will start waving his arms to protest. It is so amusing and we laugh even harder ...
Of course it always ends with us giving in and showering him with lots of hugs and kisses and that makes him a happy boy again.
