I just looked up a website and the reason it made her sleepy shall we say is because it contains codeine, promethazine (an antihistamine), and ethanol. It definately isn't colour free, and those sedating agents is probably why it isn't recommended for the under 2's. Was it the night time one you tried to buy from the chemist Nic because that may be the reason why they wouldn't sell it to you. I can PM you the website if you want as I don't know if I can post it here. It alsosays for use of moderate to severe pain only when paracetamol is not working.
If you can only be good at one thing, be good at lying, then you can be good at everything.
