I've always insisted that every child wears a bib and I have non-spill cups for each child ranging age 1 - 4. Some of the older kids are complaining about having to wear bib and they don't at home. Some also want open cups.... Am I babying them too much? It's more convenient for me the way it is now for clean up but don't want to treat them all as babies either. What do centers do? I want the kids to feel like they are maturing but not at risk of a tonne of mess. How do you handle bibs and cups and ages of children? Tx!
