Yeah, I went through this in Jan; As the ladies before have already stated, It's gonna' happen, it's natural, & there isn't anything you can do to make it stop.
HOWEVER, I strongly advise you to "try not to bother it when it's not necessary", (lacking a better way to phrase it). There's no sense in risking the chance of breaking/snapping hairs, when it's already shedding.
Don't worry, mothers on this board have gone through it; personally, I was so emotional about it; I thought I was going to be bald, but I'm not. If it's postpartum shedding, it'll eventually stop.
God Bless,
