Thank you so much for the quik replies! did the cold facewasher straight away and its gone down a bit. Doesn't help that he's been super grizzly all week, suspect teething. But he doesn't seem bothered by the head bump. Will keep an eye on it because it was a hard knock, he was having a tantrum and threw himself back as they do, and well the gas metal point was where he flung his head.

I did do the child/baby red cross course before DS1 was born but that was 4 years ago now, i should do a refresher because i had a total mental blank, but had a feeling ice wasn't okay.

Thank you so much!
