Sippy cup do's and don'ts
When using a sippy cup, here are a few things to keep in mind:
Do have multiple cups. Your baby may have days when he’s picky about which cup he wants.
Do look for a sippy cup made with an easy grip, a weighted bottom to keep from tipping, and plastic material so it won’t easily break.
Don’t rely solely on the spout of a sippy cup. Try to sometimes use a regular cup. This works different mouth muscles, helping your baby develop yet another skill.
Don’t let your baby carry the cup everywhere he goes, and don’t put your baby to bed with the cup. Doing this may lead to overfeeding and cavities.
