Just so you know...
NOTHING has been more stressful in parenting than figuring out the cup progression. Food was not this difficult. There are not that many variations on a spoon. But cups...OH HOW I HATE THEE. I have sippies with plugs, I have sippies without plugs, I have juice boxes. I have flip up straw cups, screw on disposable cups with straws, disposable non plug sippy cups. THIS is why I have a 2 year old with a bottle. I am cup overwhelmed.
Lots of encouragement I am!
