Wipe those hands
With the FAA's restrictions on liquids and gels, many of the things parents tote around for their tots - hand sanitizer, bug spray, and sunscreen - cannot be carried on planes. Luckily, many of these come in nonliquid form. Sani-Hands antimicrobial wipes cost about $3 for 24 individually wrapped packets. Insect repellent with DEET (by Cutter, 20 for $4.49) and without (by Bite Blocker, 20 for $8.19) are available in wipes as well. And towelettes premoistened with SPF 30 sunscreen by Shady Day ($13.99 for a pack of 15) are waterproof and sweatproof. They are available at drugstore.com, amazon .com and at many grocery and drug stores.
