Diaper Rash Cream
A standard-size tube of diaper rash cream fits the 3.4 oz carry-on liquids rule, and larger sizes are still allowed as a declared baby-care item.

Carry-on details
Allowed under the liquids rule, with a baby-care exception for larger sizes. A diaper rash cream or ointment in a container of 3.4 oz (100 mL) or less fits in your quart-size liquids bag like any other toiletry. Larger containers are still allowed in carry-on as a declared baby-care item exceeding the standard limit — tell the TSA officer you're traveling with a baby, and expect the tube or jar to be pulled out for separate screening.
Checked-bag details
Allowed in any quantity. Diaper rash cream has no size limit in checked baggage. Pack the tube or jar sealed in a bag, since creams can leak or get squeezed under the weight of other luggage.
Quantity limit
100 ml (per container)
Special instructions
If you're carrying more than 3.4 oz (100 mL) in your carry-on, declare it to the TSA officer as a baby-care item exceeding the standard liquids limit — it qualifies for the same medically-exempt screening as baby formula and breast milk.
