Worst Mom Award

So I seriously feel like the worst mom. Today I went over to a friends house and I brought Paxton with me. She had her fireplace on and I didn't think anything of it. I put Paxton down and walked over to the kitchen and put my stuff down. And before I know it Paxton is crying and I look over and he is sitting next to the fireplace. I knew instantly that he had touched the glass. I walked over and his hand was bright red and he was shaking it crying. I immediately ran it under cold water and that seemed to calm him down. But he decided he didn't want me running it under water anymore. I tried to get him to hold a cold rag but he refused. He just kept looking at me and crying and saying mama. So I got some burn ointment and stuff to wrap his hand. He doesn't like it but hasn't figured out how to take it off. I tried to put him down for a nap and he just cried. He has blisters on his palm where he touched the glass. I feel so bad how could I have been so dumb to not think about the fireplace!! So I have spent the rest of the day holding him and loving him because that is all he wants. He gets down to crawl and puts pressure on his hand and then lifts it up and cries. I wish I could take away the pain I know how bad a burn hurts and that makes me feel so much worse.
