LOL. Ok, too funny! I share your hate of sippy cups. I really do. Unless it's a toddler, be gone with those horrid things!!
I actually have a suggestion. Amazing, eh?!
When at family homes, simply ask for them to use a regular cup. Assure them that Mo will sit down at the kitchen table when he is drinking. No bringing the cup with him. He sits down to drink, and if he wants to go play, he leaves the drink there.
This is what I do when kids visit my apt. "Apt. Rules". :wink: Being a single gal, I don't want kool-aid on my stuff, but I also want the kids to have treats and stuff. Works well.
Still laughing......ridiculous sippy cups.
