My soon to be 7 DGS looked like a snake as a baby with almost scales on his body.
He was given all different creams from the doctor and specialist. Things will improve but you all have to remain patient.
A few tips make sure when your DGD is bathed that you don’t rub her skin when drying her, just gently pat her dry. Keep her cool my DS still has a fan in the room which is used three quarters of the year. Mittens to stop the scratching. My grandson liked to be naked with just his nappy whenever possible. Only cotton clothes to be worn. If her eyes are gooded (if that is a word) in the morning make sure that her eyelids are gently cleaned from the inner part of the eyelid (by her nose) and wiped outwards. Always use tepid bath water.
At one time our grandson had about 50 warts behind his knees, which the doctor dealt with and now he has clear skin. It was very stressful for us all.
I was taking him to school the other day on a really cold day and I said ‘you should be wearing long trousers’ he replied ‘No I like to keep my skin as cool as I can’. In other words he self monitors his skin.
As time goes by the specialist will identify foods that your DGD is allergic to but we find all restaurants cater for allergies. My DGS is allergic to fish, eggs, sesame, soya, coconut oil, nuts but he is still a healthy young lad who plays football and leads a good life.
Things will get better just hang on in there.
