This is only my second rodeo, but, best I can tell, parenting in the first year of a child’s life is a succession of preoccupations that are as all-consuming as they are fleeting. Latch, supply, weight gain, suspected intolerance (?)4, wake windows, back-to-stomach rolling, sleep regression, solids. It’s hard to overstate how important these things feel, or how briefly they feel important. A friend who gave birth just six months earlier is no help. She is in the throes of a subsequent fixation.
