Since they were little, when any of my kids bump their mouths, or have a sore lip, instead of giving them an ice pack, I’ll hand them a popsicle. They get distracted from their pain by the sweetness, and they are more likely to keep ice on for longer when it’s flavored! (And bonus if it’s red – if they have any bleeding, they won’t notice the blood — and we all know that kids will start crying anew if they see blood!).
When we have them, we like to use our own frozen pops that we make with fruit and juice — then they are getting some vitamins and fiber with their treat. But when we don’t, a pre-made popsicle will suffice.
I even still use this trick with my 15 year-old daughter, when she eats something particularly crunchy and cuts up her mouth.
