My baby's got the fever! My favourite chapter from Simplicty Parenting has to be this one. Keeping the little ones held close and quiet when the fever erupts seems to help sooth this particular growing pain (adults get these too by the way). Like a physical fever, when it passes, if you look close enough you can see traces of growth spurt spurted.
There is a parralel between tranistions and more bouts of soul fever. I can see that at work here.
