My swine of a son pinched my boob this morning really hard after I upset him (i had him wrapped up in a blanket and kissed him.. thought he was laughing but he didn't like it so was a genuine mistake!) I was so cross (and sore) that I gave him a little pinch back on the arm.. he cried forever, which he doesn't usually do.. now I feel awful..We made friends but I still feel guilty.
