You can even add the med’s to 2.50 oz’s of milk instead of 5 and still would be able to tell how much meds your child has had if you work it out.  I.e. say I added 5mg of hydrocort to the 2.50 oz bottle of milk.  This means that for every 1/2 fl oz, there is 1mg hydrocort.  So I can assume that for every fl oz the baby takes that they have had a total of 2 mg/ml hydrocort. Simple.  Whatever the breakdown--- if you always give the meds in a smaller quantity than the baby normally takes, then you can be assured that 9 feeds out of ten, they will drink that and whine and want a top up.  So you just make some more up.  I made Ashley’s milk up for the whole 24 hours in a huge sterilized flask and would just shake it and take the amount required to either give him a dose or give him a top up. 

I am all for ease and for making them comfortable and if a baby doesn’t like the taste of meds, then your as unsure how much they have taken when you dose direct as if they spit up, your are left wondering exactly how much they spilled.  Atleast when he spilled up out of a bottle, half way through, I knew exactly the amount he had taken, the amount he had not taken and I could then decide--right, he definately only needs to be re dosed 2.5mg as thats all he has spit up---so I would go and get the medicine bottle and put in another 2.50ml of suspension, then clean him up and start all over.  Since babies spit a lot and parents generally dose before a feed if you give them the meds and then a bottle and they are in a spit up mode--- you have to assume they spat the whole lot up and re dose.   So I always thought my method was the bees knees really and knew exactly what he had had before he spat up.
