My friend Angie is staying with us this week from Phoenix. She & her husband have four children ages 5 & under (and another one due in 3 months), so I've been looking forward to collecting mommy secrets from her.
Instead of labeling sippy cups, she has assigned a color to every child. So she buys cups in 4 different colors and each child knows his/her color. Their sweet girl always has pink, of course. But each boy has his own orange, blue, or green cup. The kids never get confused & drink out of someone else's cup, and mommy always know which one belongs to who!
I love it - so easy and no sharpie marker labels that wipe off!
