Sunmamma, YES I am looking forward to reaching the new equilibrium someday! We will hold that hope in our hearts! (Feeling liturgical since it's Advent!) 
Heatdodge-- oh, I hope it's not PPD. Motherhood is so crazy anyway. I just finished changing three diapers in ten minutes, spilling half a gallon of hydrogen peroxide on my bed, screaming at the kids for getting at each other every time I go change the baby, and collapsing in tears with screaming baby in my arms... then the baby goes to sleep and I hear the three big kids (10,6,4) getting lunch ready and singing "Angels We Have Heard On High" together in the kitchen and feel like I should be happy about that, but I'm still all torn up inside from yelling at them and from the baby being upset. I feel like things change too fast to adjust to. (pardon the grammar!)
In retrospect it might have been a good idea to stock up on independent things for them to do, before the baby came. I just didn't think of getting them anything since I know they will be inundated with Christmas gifts from their grandparents so soon. But a nice snap-circuits set, or some new Legos or something might have been just the ticket to a calmer life right now. Maybe I'll add a few things for them to my online order of things for DH's family (thankfully my family doesn't do gifts). On the other hand, I'd REALLY like to simplify our life and especially clothes/toys pretty soon. Hm, maybe I'll just make them some salt dough to make Christmas ornaments with, instead.
(Easy postpartum salt dough: Mix 2cups flour, 1 cup salt, 1cup water, 1T. oil.) And maybe I should add a few drops of lavender to that to calm everyone down!!
