well so much for fabulous

i fed timmy exactly like i have been and he threw up this morning and i have NO IDEA why this time. We think his problem is gulping/gas..but how does that make sense when i was feeding his kibble one piece at a time and stopping to let him burp

before giving him more. The most he had was 2 pieces at once which i didnt hear him chew, but thats a bit of a stretch..2 pieces! im hoping this was just a fluke of some kind, cuz we were doing so good..but it does have me a little worried that there is still another reason.
