OMG what have I done to my baby!
Here's the story:
I went to go to mothers group, but it didn't look like anyone was there. So I drove to go to the waterfront have a 10 min walk then head back. But I stopped at th Lota Creek Mangrove boardwalking area (on Whites Road - for those of you in Wynnum QLD). However, I thought that it was just a walk to a lookout of sorts. No, it went right thru to another road. There was also a trail, so thinking it was a 10 min trail, I decided to take it. 1 hour! Most of it was under trees. When we got back to the car, I was hot and sticky and itchy and decided to go home for a nice cold bath. In that bath, I saw that Jensen had a bit of a red arm. Hoping to delude my self that it wasn't sunburn, I thought it may have been more of his heat rash/ other rash that he has. After 2 hrs, in which we both napped for an hour, I noticed it definately sunburn! And its bad... spesh on a baby. Its on both arms and legs, one side more than the other. And a lil on his cheeks.

OMG, what can I do? I put some sorbolene on it but I rang DH and he said to go and get some aloe vera, preferably a plant, and put that on him. I mentioned that when you're sunburnt you tend to be more thirsty, and atm, I have this feeling that he's just not getting enough from me - but thats another story. DH said maybe some cooled boiled water if he wants it after he's been breastfed.

What else can I do? I feel so terrible that I've done this. He's only just 5mths old and already his first sunburn. Not really something to put in the baby book.
