I hope I'm doing this right. I put 1/4-1/3 dropper full into two cups water to treat all my babies. Since I have one with pneumonia, I do not want to take any chances. I just picked the vitamins up today and I am using the poly vi sol(no iron) infant drops. Also, since day one I've put probios in their water as well. Is this too much vitamins? I hear of people putting a whole dropper full in the waterer. Since I premix mine in water bottles and change the water several times a day, I do not fill to the top of the waterer. My 5 week old got pnemounia from eating too much pine and getting stuck in her crop. I have her on antibiotics. I thought maybe the vitamins would speed up the healing process.
