I use a nurofen dispenser also a fair way back to the side of her mouth and i leave the dispenser in her mouth for a few seconds aferwards so she kind of has a suck and swallows it all down. I think it makes it a bit trickier to spit it out with something in her mouth I also find that having her on a recline rather than sitting up helps.

HOpe that was somewhat helpful. My DD is now gulping it down like it's some special treat
