I am writing about my 9 month old son. I had socks on him the other night when he went to bed (he kicks the blanket off, so I try to keep him as warm as I can). I happened to notice a small red line (just looks like a small red scratch) which I figured was from the socks leaving a mark. Well it's been a few days and it is still there so I read up about it a little online and seen that this can be common with babies and the socks. My question is will it go away? The way I'm understanding is that it's somewhat like a bruise underneath the skin or broken blood vessels. Also, is there anything that I should be doing, ice, warm cloths, etc ? Hes in absolutely no pain from it and like I mentioned its a very small red scratch looking line on the back of the calf. Thank you!!
