Little Puggle is in Bumgenius so a pretty small fluffy bot but a vest extender would just let him get a few more weeks out of some lovely barely worn Gap things....but the standard vest extenders don't fit the poppers! Anyone found ones that do?
Try eBay, for some rectangle shaped ones, I bought some off there a couple of years ago and the listing said it worked for gap/zara and a couple of other brands. It's not in the title though so you might have to go through item descriptions for a few listings...
I got a kit in a local craft store when I was making bandana bibs for my slobbery baby,and it wasn't dear. Just a bit fiddly and came with all the fixings. I just had a look on amazon and there are similar ones for under 6 pounds. Or fancier ones for about £12.
I had a few things from baby gap when ds was younger, am I right in thinking they are really teeny? Or was that h&m? Either way I've seen really small studs on eBay and amazon, but you might have to buy the bit to put them together separately.
