Now I am really wondering something here. You said he was 10months and 18 lbs? The maximum dose for his weight was only 2? Graycie is 14 months and 19 lbs and she is on 4 with meals and 2 with snacks. She has been on that many for quite a while. Do they use a certain formula to determine the amounts? Sorry to hi-jack this but I really don't understand how Grayson could be on such a higher dosage. The lower dosage and increasing the prevacid didn't help her, could that be way such a difference? She still has alot of bowel movements and they are never ever, solid. Could shortgut be the difference? Once again so sorry for grabbing this and running but now I am alittle concerned.
