Staying home for a good 2-3 weeks solid is the best way to set up a routine for your LO.
When you have a solid routine in place it'll be easier on you and your LO. We go out right after DD's naps and try to be in before her next nap. If your LO has to sleep in a carseat or stroller once in a while thats ok. But if you have this solid routine in place it'll be easier on your LO and wont cause as much overtiredness or overstimulation.
