Purple hands

[Laserbeam24]

I've tried searching for others in my position but haven't found anyone yet.

My baby is 8 months old. Every single morning she has purple hands and feet. Hands tend to get better by the afternoon but feet stay purple for longer. I thought it may be temperature related, so I increased the house temp and put her to bed with her babygrow folded over her hands, and mittens on top. It's made no difference.

She saw the paediatrician at around 4 months for unrelated matters, and when I brought it up I was told it's a sign of a healthy circulatory system. Now she's 8 months I feel that it's something she should've grown out of by now.

I know that this is normal in newborns. Anyone else have a child who does this at this age?

Raynauds syndrome maybe?
The doctors told me my DS had this when he was much younger but didn't say we had to do anything about it.
He seems to have grown out of it (he's 12) but his hands and feet do sometimes turn blue when he's cold

As a PP mentioned it's not unusual to have this as children's circulatory system is not fully developed.
I had it with my DC whenever ill, their hands and feet would go purpley. The dr checked her 2 or 3 times and said that the body was focusing on fighting the infection and so the blood flow was often directed from extremities. Also mentioned this wasn't unusual up to the age of 2-3
