ok this will burn will like crazy for a few moments but it will take the heat out of the burn and make it go away quicker.
put vinegar on the sunburn ( apple cider kind for better smell) then after you have soaked it in the vinegar sooth it with aloe gel. If its so bad it cant be touched you will definately want to do the vinegar thing.
I have gotten to a point were I use vinegar first no matter what then aloe.
If it releases to much heat or your afraid it might, mix it with water in spray bottle and mist it and have a fan blow on them.
As far as grandparents go...
I think we have all done it. Be super relieved that the kids are entertained then realize " OH
," we forgot something. Then we feel terrible about it and kick ourselves that it was something we told ourselves over and over again we were going to do or not do.
If someone reminds us that we were suppost to do it we already feel stupid about it and get defiant.
No wants to hear "I told you! a speeding ticket for going to fast."
Time flies when you are having fun and enjoying someones company.
Have you taught your kids that they need to apply sunscreen? (general for parents who can and something for parents who kids are younger to look forward too)
that way they can be responsible for thier care and safety too.
