I know this is an old request....but it was in the spotlight on the side of the Mamasource page.
I just wanted to share a strange allergy...it is not to detergent. It is to irritation.
Your cells individually release histamine when irritated.
If you notice when you get a bad scratch, sometimes it gets red and blotchy...and sometimes even weils up ike a cat scratch would.
Well....I happen to have an allergic condition that makes me do that all the time...well...when I am not taking antihistamines for my hayfever.
At night, the heat changes make my legs itch....but if I scratch them once, I can't stop. I get it when I take off tight clothing....stockings, socks, the waist band of jeans...
Once I was going nuts thinking one of the children in the house had head lice. I checked my daughter and my friends kids...none of them had lice....so then I had my friend check me....well I did not have head lice either. But it felt like something crawling on my head....biting, itching. EEEEwwwwwww.
I noticed some time later that after brushing my hair, my scalp was on fire....crawly itchy feeling....drove me nuts...My entire scalp was red....right to the hairline.
The hair brush scratched my scalp all over and caused hives all over my scalp. I couldn't stop scratching....but the more I scratched the worse the hives got.
Since I have hayfever, I see an allergist annually...I asked him about the hives....he played with my skin a little. It's sort of funny, the slightest scratch maked me look like I was attacked by a cat. I never noticed it before.
He said it is called dermatographism (something like that).
It makes me look awful if I scratch my cheek....
lol
But I choose not to live on antihistamines year round.
The hormone changes in a baby could cause that temporary immune response....or it could be a sign that he may have sensitive allergies.
SO...if you find nothing works....you may have hit it right on the head the first time, holding his arms, forcing him to stop. It goes away on its own when it is no longer irritated. Calamine topically will sooth too, but may get messy. Antihistamines prevent it, but I do not recommend medicine for babies when it is not absolutely needed.
Congratulations on your new baby!!
