"Sent home, returned the next day"

My 10 month old son was lethargic, had a high temperature, a wheezy cough I could tell he wasn't himself. He was bought to barnet a&e by ambulance. I waited in the children's a&e section for 6 hours! When we were finally seen I was told he had gastroenteritis, to give him water and go home. The next day my son turned even more lethargic, was almost unresponsive and was taking deep breaths to breath. We called the ambulance again. The ambulance staff were worried they checked his chest and said they could hear a crackle. When the a & e staff saw that we were back again they seemed to take me more seriously. They checked my sons chest, told us to go into a side room with a bed. He needed oxygen because he couldn't breath properly. They did an x ray quite quickly. My son had pneumonia and had to stay in the paediatric ward for a few nights as he needed antibiotics and close monitoring. I know A&E gets very busy but I was surprised they didn't priorities younger children as my son was only 10 months old. The paediatric ward my son was taken to was very good. The staff were supportive. I was upset that we weren't taken seriously the first time we came and if I didn't return the next day who knows what would of happened.
