Baby has rash and skin is pink with sores

Greetings<br> My son is 11 months old now his been using pampers since he was born and have Neva had any complaints few weeks back I saw an advert about the huggies Pull ups for boys and girls, I was impressed so I boht them at checkers, it's not even a week already my wife called me to see what the huggies are doing to my child's skin, he has a terrible rash and between his thighs he is pink like a skin irritation, am really disappointed at huggies it's a big company and they should check all there products before shipping them out, and am not the first to complain about this I saw complains about baby rash from huggies products, why spend so much money to have regrets, I will be going back to pampers but am not going let this go, my child's health became an issue because of huggies product. And I did buy the right size. Am going to take them to a professional to check what is wrong with them, and take it further.<br> Really disappointed
