What I think, and what I wrote in the comments, is that different babies have different temperaments and adaptability tolerances. Some babies are hardly phased when 2:00 rolls around and they aren't being set in the crib like the past several 2:00s. My baby isn't one of them; she needs a routine (all babies do, of course, but people. Wynnie don't play.), and when we're out at naptime or even when she wakes early from a nap, she is incurably cranky. It's not fun for her or for us. So I am loathe to disrupt her schedule. Occasionally we do, to visit friends or go out to eat with our families, but Mike and I both know we'll pay for it later, so we keep outings to a minimum. To us, it isn't worth the fussing or the day or two it takes to get back on track.
What I didn't write in the comments, because there's no need to broadcast your snobby dissenting opinions on someone else's blog, is this: I think it's a mistake to believe that as a mom, your life doesn't revolve around your baby and her needs (and other children too, when applicable). That may seem extreme, but I come by it honestly. My mama is a routine snob. Any time we're out and hear fussy crying babies or cranky meltdowny children, she says "that baby needs a nap." or "that child should be in bed asleep." When Emily and I were babies, Mama strove (strived?) to have us at home for naps and in bed at the same time every night. She almost never took us on playdates, shopping excursions, or visits to friends and former coworkers. I don't even think we did the church nursery, though I could be wrong. And I'm sure it wasn't much fun for her some days feeling trapped in those wood-paneled walls with two needy children. But what's that thing people are always saying about parenting? "It's the hardest job you'll ever love?" It's corny, but it's definitely true. Being a parent gives you a million new ways to make sacrifices, and for my money, sacrificing your schedule to your baby's, at every possible turn, in order to have a happier baby, is well worth the boredom, difficulty, and juggling it can cause. I don't want to step on any toes or criticize anybody else's parenting. I think routine is more important for a happy, well-adjusted baby than anything else, but some people may disagree, or may not be able to stick to a strict schedule as easily as we can, and their kids usually turn out great. All parents should do what works best for their family.
Of course, with a 2nd baby this is all out the window. Beyond 1 child, as best I can tell, survival is about all anyone can hope for.
