put two drops of pancake syrup right on her tongue in case she is hypoglycemic and let me know if she perks up - I will stand by.
Your baby may have had a seizure. This can be a result of a parasite, an ingested non food item, an illness, etc.
Since she responded to the syrup that mean her blood sugar was low. Keep her very quiet. If she has a fever wipe her down with a cool damp cloth and immediately wrap her in a towel so she does not chill. If she cannot keep anything down or the seizures continue you will have to take her to the ER. In the meantime if she acts lightheaded do the syrup again.
Please let me know how she is and if you have more questions. I will be happy to help in any way possible.
