My 15m has started spitting up occasionally after drinking from his water cup. I have noticed it a couple of times in the last few days. He will drink his water then a couple of minutes later it will come out, sometimes with a bit of food. It’s not forceful/vomiting and doesn’t smell or anything, it’s just like a mouthful of water with bits of whatever he’s just eaten. I initially thought maybe it’s a bug, but surely he wouldn’t have an appetite/wouldn’t be himself or would be more forcefully vomiting? It’s really odd. Has anyone else’s little one done this? It only ever seems to be after drinking from his water cup
