Have been using Oilatum since a couple of weeks, as his skin was always quite sensitive. But now found definite patches of eczema on his legs. Luckily it isn't red or sore, but it is definite eczema. DS1 has it pretty bad. It runs in my family. I don't really have it, although occasionally will find one small patch of it hiding on me somewhere. It doesn't bother though. Hopefully it will just be very mild for O.
His skin is very easily irritated though, if he has a hat on, he has bits of skin all over his forehead when you take the hat off from where it has rubbed off! Also, if you touch him, it leaves a red mark for a few minutes. His skin is very thin, you can see all his veins. Poor bugger!
BP I read that you should take them to the GP early if it hasn't corrected after birth, as treatment needs to be started sooner? MIL told me today that all the males in the family have had one. DP and I both do, his is corrected with glasses, and is always there. Mine is corrected with glasses, but it only comes up when I am tired. So O is highly likely to have one too.
