This is the first time I've seen him choke on his food. He seemed to be eating a bit faster today than usual so that may be the reason. I'm concerned he's moving into a new stage and wonder how others have approached this. He seemed fine after a thump on the back (then had to blow his nose!) then went with me for a short walk up and down the driveway. Will this problem increase quickly or will it be an off and on thing?
