We have 3 kids (6,4, and 5 months). For the general 30,000ft view. Follow your instincts, give yourselves room for "mistakes", people's opinions are worth how much they cost.
Crying it out is a matter of your stamina. There are no studies that show one way is better than the other. generally our infants and up to about a year cried when they were dirty, hungry, or "sick". We tend to them when they cry. As they get older we tighten down the attention and our 2st two aren't issues anymore. However 1 kids refused to sleep when younger and hates napping, our 2nd will put herself to bed or tell us. Raised exactly the same.
Raise your kids how you live. The kids do what we do mostly when we do it. My wife had our first two on her chest fly fishing at 1-2 months old. We went hiking, snow shoeing, on UTV rides etc. At just over 1yrs old our 1st two we had on our backs upland hunting and in the blind waterfowl hunting and on the floor of the deer blind. We did our normal road trips and by the time they were 6months all three had been to multiple states in the car.
Your life definitely changes but keep it as consistent and normal as possible. It may take a little longer to get to where you want to go, and you may not be able to stay as long, but don't stop your life because of the kid. Snacks and even on the go meals are a life saver. Also, when they get a little older...carry a small kids potty chair with removable center.
