I totally forgot about that and how alarming it is. Glad you have your Dr looking into it but it's very normal to be shedding as if you are going bald.
I seem to remember reading in a parenting magazine ages ago that it's actually the growth of new hair that triggers the old to fall out, that during pregnancy, hair goes a bit dormant since all the body's focus is for the womb. Then after birth, it would seem like all your hair is falling out but it's not--well it is but new stuff is coming through.
I can't honestly tell you if this was the case for me, while I don't think my hair is thinner, some days I feel I can see my scalp on top all too well but then that's age too (ouch my creaky bones!).
I think the hair exodus stopped around 6mos pp but don't hold me to that.
hugs to your sick wee one. Hope his ear infection clears up quickly. It helps that you are nursing.
