Sarah (now 5) was having a sore throat. Quick strep test came back negative, so a virus was suspected, and the doctor said to keep liquids going in. Sarah was perfectly willing to eat popsicles all day long, but somehow I wasn’t convinced that an all-popsicle diet was in her best interest.
So I filled an ice cube tray from a bottle of lemon-flavored water, and let her suck as many lemon ice cubes as she wanted. I tried to make them small, but she still wanted them smaller, so I would put one in a ziploc bag and whack it into chunks.
Next day, her throat was all well. Mission accomplished!
This ice cube tray makes cylindrical ice cubes (for slipping into bottled drinks) and would be a good choice for this hack, I think.
