Mary Catherine and Henry love dip. In our house, 'dip' is anything that you can dip something into like syrup (agave), ketchup, ranch, sour cream, etc...
Of course, I would prefer they don't use any of those because they are messy and sometimes sugary. However, I give in because they see the other children using them and starting squawking, "Dip! Dip! Dip!" incessantly and poking their trays where they want me to put it until I deliver.
Thankfully we rarely use ketchup and that's the worst of them all. I've read that ketchup has more sugar than ice cream per teaspoon. Yikes!
