You can slowly work towards braille without overtly using braille. Adding some sort of unique tactile feedback to spice jars for example. While you can certainly add a braille label to them, you can also just use embossed jars/lids, or stick multiple nibs to the top (1 nib = salt, 2 nibs = pepper, etc). Getting them used to tactile feedback being a good thing to look for can go a very long way to accepting that braille is an enjoyable next step.
