My oldest son started camping at three months of age. Camping trips rarely go perfectly the first time - but you can avoid a lot of serious complications with a bit of practice and planning. The first camping trip should be a short two night adventure near your home. This allows your infant the chance to become comfortable with the outdoors without over-doing it. A long trip can become disorienting for a baby or young child.
Children have to adapt to long car rides.
This takes training and patience. Pick a spot without extreme temperatures. Even tiny babies can put up with almost anything you might expose them to - but you will have to work harder to keep them comfortable. I find heat is the extreme to avoid. Infants under six months old should not wear sun screen unless your pediatrician recommends it.
