Generally at what age are you transitioning kids from sippies to open cups for milk?
Most of mine have been around 18-21 mos depending on oral motor skill level and whether they spill all of the time. I have a parent of a 10 month old that was advised by a medical professional to move to open cup immediately and get off the bottle. They were told to skip sippy cup. I have never known a 10 month old to have the oral or fine motor skills to take 5-6oz in an open cup. What age do you move them to open cups? Thanks!
