OMG! I am so sorry you have to go through this. I mean, I know it isn't lethal but it is still horrible to see. I have gone through this before, which is why I took it upon myself to groom Louis. I would have not paid for this, but when it happened to me I did. I don't know why I did and why I just didn't go all off, but geeze! I'm sure some sweaters will do until the baby's hair grown longer.
Sending hugs to you (sorry about your thyroid)
