you can always give him some plain non-fat yogurt. that helps with upset tummies and antibiotics

and i agree, standing up on his own and walking around is fine. what you don't want is running, jumping, playing, stairs, and bouncing up and down on his back legs. also do not put him on furniture. sit with him on the floor instead of him sitting with you on the couch. it only takes 1 second of not paying attention to him for him to jump on/off the couch/bed and break a leg. i've seen it happen. its not pretty
