Covered in sick and out of explanations

After the teething revelation I calmly administered Bonjela, to soothe the pain enough to then give 2.5ml of Calpol, which Felix kept down, then I waited 20 minutes and fed him. And he seemed calmer at first, but it's only been an hour and he's back to intermittent moaning and crying, and he just vomited over top number 3 today - on the inside - which is nasty, but I can't be bothered to change right now, so I'm back to feeling like I haven't got a clue what's going down and am resigned to holding him and trying to ignore the noise and smell of baby sick.
