I believe they let you carry travel sizes of some of the above. I would recommend not putting in anything u can live without on the plane, e.g. sunscreen. For baby food they make u take a sip. They would not allow water in a baby's bottle.
Also can someone tell me if I need to get any vaccination before leaving the country. Is there a rule that I cannot enter back to usa without having vaccination?
sorry i haven't traveled after the 911 incident and I am totally a dumbo on this.
