Sunburn advice

Hello,

My 15 month old daughter has got sunburn on her arms 🥺

It was a warm day and she was in a short sleeve vest. She wasn’t in the sun long at all, we were at a car boot sale and even tho we had an umbrella on her pushchair, when she was out of it she was unprotected.

I was only looking at sun cream for her last night.

I am truly feeling like the worst mumma ever right now even tho it doesn’t seem to be bothering her 😔

What can I do to help it? I’ve made sure to keep cool water on her arms when she had her bath and moisturised it.

My issue is that due to allergies she has very sensitive skin and has really bad eczema so I’m cautious not to use anything that could cause a flare up.

Also what sun creams are the best for babies with sensitive skin? I’ve had a look online but I’m wondering if anyone has one they recommend?

Thankyou
