Thought I'd post a quick message about this Daysack. I've been having a few issues keeping my 2.5 year old close by, now that he doesn't want to go in his buggy very much. It's more of a confidence problem for me really. I get very nervous if he is running around out of the buggy. I also have a 6 month old so I've got my hands full!
Bought this - see this link for details:

We've called it ds1's "special bag". He loves to wear it, and I love it because it has a rein. It's also got an additional loop on the top in case you need to grab him quickly.
It's more grown up than traditional toddler reins and just gives me that extra reassurance. Since he's worn it, he's also been better in that he's not been quite so keen to run off, and also walks next to the buggy voluntarily!
Thought I'd share it with you.
