Baby formula, breast milk and juice for infants and small children are permitted in reasonable quantities in excess of the 3.4-oz. carry-on maximum for other liquids. Try not to bring more than you need, as the TSA representative at the checkpoint will decide what constitutes a reasonable quantity.
You must carry liquids intended for babies and children separately from your other carry-on liquids. Unlike your other liquids, these are not required to be placed in a clear plastic zipper-top sandwich bag, but this can expedite the process.
When you reach the security checkpoint, inform the TSA representative if you are traveling with liquids contained in baby bottles or toddler cups.
Be prepared that baby bottles will undergo additional inspection at the X-ray terminal.
Mothers traveling without their children are permitted to carry on breast milk in reasonable quantities as determined by TSA security personnel.
The TSA asks travelers to bring only the amount of baby liquids needed to reach their destination.
