I'm like that with Pixie, she's does something naughty, which is quite often at the moment! (she's going through the teenage delinquent, rebelious stage
) I tell her off and i'm mad with her for like, a second! but her little face just melts me and she covers me in kisses as if to say, 'sorry mummy! REALLY i am!'! LOL
I had to laugh at your MIL kicking the poop though...how funny!
