Hi was wondering for some advice. My newborn was 6 weeks yesterday. On Thursday he started spitting up milk a lot more than usual (currently suspecting reflux) but on this occasion all day it was more than normal. Just recently started on carobel Then on Friday he seemed to be sleeping way more than normal. He stopped waking for feeds I was having to wake him. Saturday he was the same. Saturday he had a loose BM and his cry changed just very weak and high. I contacted out of hours they advised to monitor cause he was still having wet nappies, and no temp. Woke up on Sunday morning no change so took him to hospital they checked his belly and because he was alert at the time felt he was ok. We went home and by that night I notice we red like spots on his chest so I took him back to hospital and we were admitted. They felt the red spots could be from being sick wee blood vessels. They done tests for covid, rsv which came back normal, they done bloods on his foot and then bloods from his wee hand. All came back normal. Urine also dipped and normal. So they said it could be gastric infection. I do currently have a sore throat and a runny nose so he may have some infection. However would this not show in his bloods ? Also if that is the case how long will he big like this ? When should I take him back if not better ?
