I always put Ashley’s medication in his bottle as a baby and there were absolutely no problems.  It’s simple...you make up a smaller amount of milk than your baby takes.  Say they take 5mg hydrocortisone.  You make up 5 oz’s milk and add the 5 mg hydro and shake well.  baby only takes 3 oz’s...that means baby has only had 3 ml’s hydrocort.  You then make sure they get the other 2 ml’s by syringe.  That’s on the odd but rare occasion that they don’t drain that small 5 oz bottle of milk, which rarely occured for us.  He drank every drop and then another bottle with just milk would be then warmed and given to "top him up" so to speak.  That’s how you do it basically and feel sure they have had the whole med’s.  I use to slap the HCT, florinef and sodium into the bottle and he never flinched.  Up to that point before we started doing that at 6 mths, Ashley always spat his med’s out--so (LOL--no joke---every single time without fail--and he would bawl the whole house out--he never got used to the taste of the meds directly given to him---suspension is very bitter and a lot more bitter than tablets due to it’s being broken down) we never knew how much of the med’s he had had or not had so to speak.
