does anyone else have these teethers and notice that the only ones that will freeze are the yellow and blue one? i put these in the freezer for my daughter and the red one will not freeze and i just find that so weird!
You're not supposed to put them in the freezer, just the fridge. It may break and the baby could ingest the liquid from inside. I know that's not what you're asking, but I thought I should say it anyways.
