It's not easy to go out with a Baby. This is obvious to the parents out there, who are cheerfully laughing at my naiveté - I can only point out to them that they were in my shoes, once.
But it is hard. For one, there's preparation - you've got to pack the baby into the carseat, make sure you've got enough diapers in the bag and bring that along, and probably a blanket or two, this time of year. You then have to wrestle it all into the car, and take off. Upon arriving at any destination you need to unpack the baby, possibly also the stroller, and set off. Going anywhere costs extra energy just getting in and out of the car, and as you're out and about with the baby she gets tired and cranky. You don't really stop anywhere on a whim, you tend to plan everything you do. I'm sure this will ease up as Rose gets older, but it's hard.
