The skin around my 3 month olds right eye has become blotchy, red, swollen and itchy after sitting in garden. The same thing happened yesterday and I originally thought she had been bitten or stung by something but the swelling gradually went down and when she woke this morning her eye was back to normal. So today we were sat in the garden again (on a different mat) and after about an hour or two the skin around her right eye and into her scalp became increasingly red and blotchy and she has been rubbing it. I have brought her inside and been rinsing her eye with cooled boiled water which seems to have relieved the itching a little bit. Any ideas what could be causing this and how best to treat it? Thanks
