Even if your child is toilet-trained, pack approximately one extra box for every four days you'll be camping. Kids get dirty in the woods (and they should), but you'll need to occasionally excavate their tiny faces from the layers of grime and de-stickify their hands and feet before they climb into the tent with you. (Wipes come in handy for the adults, too.)
Lots of kids' clothes
Jeans and overalls can be worn until filthy (remember, this is natural dirt), but it's best to be prepared for water, berry, and roasted marshmallow debris. Bring long-sleeves and pants to help protect your toddler's delicate skin from extra sun, mosquito bites, and poison oak. Be sure to include rain gear, extra shoes, warm sweaters, maybe a windbreaker, a hat, and light gloves, too.
Child backpack
Toddlers don't always want to walk, and your hikes may turn to snail-paced strolls as the little one examines every fallen leaf, twig, bug, rock, mossy patch, and gray lizard.
Camping first aid kit
A well-stocked first aid kit might hold antibacterial cream, baking soda (to apply to stings), Band-Aids (large and small), one-percent Hydrocortisone cream, hydrogen peroxide, insect repellent, Moleskin (for blisters), scissors, splints, sunscreen (waterproof, with both UVA and UVB protection), special medication (for example, if your child is allergic to bee stings or other insect bites), teething medicine, thermometer (digital, not mercury), tweezers, and Tylenol or Ibuprofen.
Standard-sized sleeping bags
Baby bags get outgrown; consider getting your child a regular one.
A pup tent just won't do. Be sure your family can comfortably fit within your tent before embarking on your trip. Cramped quarters make for uncomfortable nights.
