ebay UK has most things in small to vast quantities so which ever bit of the universe you are in I am sure your ebay is similar

Someone here from Cute suggested a jingle bell - I bought some but have not tried it yet - sounded easy and inexpensive to me though!

Check out the cheap kitten toys at your local pet store and see if anything there might work for you. Sugartoes has several kinds of bell toys and rattle toys and loves chasing them all.

I'm kind of surprised that they are not more available. I figured that I would be able to search for them and get lots of results. Not so. BUT I did find some that are relatively inexpensive. I did find some replacement squeakers for dog toys, which should work really well for baby items if they are stitched inside. I'm attaching what I found, just in case you are interested. If you find what you are looking for, perhaps you could give everyone a heads up to cut down on search time. Good luck with your search!

I was having trouble remembering the name of the company, but finally did, just as I was shutting down my computer. If anyone will have your rattles or other items, this place will. Good luck with the search. We used to get catalogs from this company, and they were the dream books for my kids. Lots of kid friendly stuff here!

How about something like these...looks like they have rattle pods and squeekers...
