There are a few little chores like this that have to be done before this cup product is even in the prototype stage. We will need a graph showing what doses all of the assumptions deliver. For example, if you followed the age scale on the cup, and you were a very light girl (say the 3rd percentile), what kind of doses would you receive?

However, a far greater problem stymies me everytime I look at this project. I just can't seem to find the perfect dispenser for children's acetaminophen.

The mock-up cup above shows a dandy 3 tsp cup. That is about 15 ml. The problem is that in real life 15 ml is a pretty tiny cup and the scales may be hard to read. (We don't even have a cup that size, so I haven't actually tested it.)

Standard 1 oz medicine cups hold about 30 ml. The problem with going with an over-sized cup is that the action part of the cup then tends to be down in the bottom half of the cup. This compresses the scale and makes it hard to read and generally look stupid.

Let's forget the cup and take a look at a totally different device, an oral syringe. This one is from Janssen, Switzerland. It is a very elegant design, and there is plenty of room for 2 detailed scales plus a trademark. However, the size is not right here either. These syringes tend to be about 5 ml in size. (Price might be an issue as well.)
