Hmmm, I'm not sure what's going on here. Like Marci said - she is not too young for Hypoglycemia. But, after eating - I'm surprised you're still seeing such wobbliness - this is what I'm puzzled over. But, it's great that her appetite seems fine - that's really positive. So, she is still on the antiobiotics though and is still recovering from kennel cough?
If so, I would really consider those factors. Kennel cough is notorious for lingering around - and, antiobiotics can sometimes be tough on these little ones. So, maybe just see what happens over the next couple of days - and perhaps make her eat every 4-5 hours or so and see if that brings her around a bit too.
Hang in there.
