The ones you get with Calpol etc these days.
I'm sure the reason is supposed to be to make sure the dose is measured accurately but I'm not convinced it actually helps on that front, it really isn't that hard with a spoon and does the difference between 5ml and 4.75 ml really matter?
The syringes are difficult to clean, it's more plastic for landfill (because how many do you really need?) and they're fiddly and messy to use. I'm sure they lead to more waste too as I end up with medicine down the outside of the bottle.
AIBU or does anyone prefer them?
