A reader asks:

"My little girl is 6 months old. We just started her on cereal and fruits. She's mostly breast-fed, but when we give her a bottle, she holds it herself. We're wondering when we should start thinking about giving her a cup to drink out of and what we should be putting in the cup."

I have given her some advice here about how to introduce the cup and what types of cups to use. If you've already gone down this road, please leave a comment and share your experience.
