What Other Parents Ask

Q: How do I get my teen to eat breakfast?
A: Make it easy—have grab-and-go options ready. A smoothie they can drink on the way counts. Even something small is better than nothing. Don't make it a battle.
Q: Should my teen take vitamins?
A: Most teens eating a varied diet don't need multivitamins. However, vitamin D supplement is often recommended, and girls may need iron. Discuss specific needs with your pediatrician. AAP
