So sorry jameson has been puking. Sounds like he's eating something or digesting something that's making him sick all of a sudden. This summer I couldn't figure out why Emma and Wilson had started puking too, about every two weeks they'd have bouts of it, just about all summer long. Turned out they both were getting sick due to the inlet water area at the lake we had been taking them to swim. Once we stopped that at the end of summer the puking and runs stopped. They had both caught a bacteria. Hope Jameson feels better soon.
