Excellent message and really drives home the point.
Your poor husband, having to go through this.
I am surprised, and relieved, that visitors (mainly my brothers, SIL and nephews) never wanted to feed my boys anything. My older brother is naughty and gives his Cocker Spaniel fatty pieces of beef when he cooks. I will share your message with him.
The only problem I have with dad is that he drops things. He dropped a potato chip and Max scooped it up. He had a bit of a belly ache that night. Very thankful it wasn't worse.
