When my boys have needed it I have shoved it in side of cheek and pushed in 1 - 2 ml at a time.

Good luck hope better soon its hard work and sad as they dont understand need for it.

Have you tryed the icypoles?? (not that my kids would eat them either but I tryed)
I'm trying the iceblock too but i think shes worked out what it is because she put it back in the freezer saying yuk LOL
