We have the little lambs wraps, they work fine, but we also have a merino wool wrap from disana which is becoming more useful now the weather's colder. Might buy another one of those - love it! So far (5 months in) we've had no problems - they've easily contained massive poos and can go 12 hours overnight with an extra bamboo booster added. They come with washable fleece liners too, and have shown little signs of wear despite many washes! The velcro pad is coming away a little on a couple, but that doesn't make them unusable. Being bamboo, they take a long time to dry, but they also do cotton and microfibre versions - we went for bamboo as it's extra absorbent and better on the skin.
The "fill your pants" site has them on at £25 for 5, which was the cheapest I found new at the time - we've gotten by with 12 in size one... I think that size goes up to 18lb baby, but I forget! Size 2 should then technically take them up to potty training, but there's a 3rd size if needed. Hope that helps!
