M.,
Well I have a one year old that weights about 19 lbs. I recently got a Baby Hawk Mei Tai baby carrier and LOVE it for shopping.
I have tried all kinds of carriers and ended up hating all of them because of discomfort. Ring slings, slings, hip hammock, and the snuggle. With the Mei Tai I find that the weight is distributed evenly so it keeps things more comfortable. I would highly suggest that you get one that has some serious padding on the straps. I purchase one off of eBay that I ended sending back because the straps was cutting into my under arms. I was attending a Birthday party in my playgroup and was having a hard time keeping up with my 3 1/2 year old and my crawling one year old. A guest let me try on her Baby Hawk and I fell in love! It's hard to find a Baby Hawk brand for less than 80 dollars but it is possible if you surf the web. I found mine for 57 dollars on a craigs list in Calf! She accepted pay pal and it worked great for both of us.
It might be alittle pricey but I think it worth getting something made well and comfortable.
As for weight, most will carry a child up to 40 - 45 lbs though that prolly wouldn't be very comfortable. So I think with 26 lbs you should be good for one for a while. As for hubby if he's not on the extra big tummy side it should fit him fine. Also the resale value on these are very good! :)
Hope this helps,
C.
