Zirconia - Yes, that was the article I read. I don't really think it describes my LO though... He loves sweets and doesn't seem to be "affected" by them. He sleeps like a champ! Lol! He was a little high needs as a newborn, but not so much now. Thanks for letting me know that hers has faded. Since my original post, I read somewhere that it "usually" fades by age 5. Here's to hoping!
Phoebesmum - I'm so sorry to hear of your LO's troubles. Thankfully, our pedi didn't hear the murmur at his 9 month check-up. Thanks for letting me know that she's never been teased at nursery school! I feel better now. Adults can be rude sometimes. Lol! Hugs to you and your little girl!!
Possible future readers - I wrote to the authors of Baby 411 (my bible) regarding this and here's Dr. Ari Brown's response...
Thanks for writing in. That blue vein is just one of several blood vessels that supplies the face--no specific name. In general, they tend to fade over the first year of life but can be fairly prominent in fair skinned kiddos, like yours. And when kids get older and develop more fat in their faces, the vein will look less visible just under the skin.
I wouldn't worry too much about it being prominent, but if it is truly getting larger or raised, the concern would be a vascular malformation, which could be evaluated with an MRI. Not worried about heart murmur being related to it.
