A blood glucose of 88 is is the normal 70-120 range (Lady is a diabetic so I am obsessed with blood glucose
), but since you had just given her Karo syrup it probably was lower to start with.
She shouldn't still be wobbly and out of it though as once their sugar goes up, they feel better right away. Is she eating well? Karo is a quick fix to raise blood sugar, but she'll crash again unless she has a meal as soon as possible afterwards.
I'd repost your question in the Breeders section. I think you may get more help there.
