I know you're specifically targeting a market, but it may be a bit too niche (but you know your market better - it may be quite big!), and you might want to try casting you net a bit wider. You may want to add 'baby bibs' related tags for good measure.
Here are some tags I found:
- baby bibs handmade
- baby bibs personalized (if you offer them)
- bandana bib
- dribble bibs (I think this is a particularly good one)
- toddler bib
- baby bibs girl
- baby bibs cute
- baby bibs boy
- baby bandana bib
- teething bib
You can of course keep your descriptions and everything focused on disabled people, but your bibs can be used by others as well, so why not?
Also, remember that your tags are what people have to be searching for to find products. For example, one of your tags is 'swallowing problem', which is not really something a customer (emphasis being on 'customer') would search for (I did a search and there were very few results). If a person did have a swallowing problem, they would come onto Etsy looking for a particular method/product to help them, so think along those lines.
All the best! :)
