you poor thing - I remember that happening .....they sure can get it EVERYWHERE - you'll probably find it in places you didn't spot yet in the days ahead - Once that happened in my house and ALL the toys on the toy matt were covered with it - they try to run away from it or roll around to get it off them and man can it spread !
I bet the brisket was too rich - I give mine bites at dinner now cause I can't say no to those eyes....but they seem to have stronger tummies when they're older...but you're right - NO people food is best - I just happen to be a whimp
Hope your baby feels better - it may not be over yet !
