If Cobalt were mine and weighed about 6kg he would get 3ml of Safeguard for 5 days in a row *and* a metronidazole tablet twice a day. Birdbrain, my offer still stands, I'll mail it to you if you PM me your address. Talk to your parents first, of course, and have them call me first if they want to. You have my number.

Not to change the subject but, how do you dose the metro tabs? One tab twice per day? Is that 250mg?
Do you have a recommended dosage for say 2 month olds?
I would weigh, then dose at no less than 30mg/kg once a day and no more than 60mg/kg twice a day. This can be done by putting a 250 mg pill in a 12ml syringe, then draw up water to the 10ml mark. Now one has 10ml of water and each 1ml has 25mg of medicine in it.
