Hi, we used cloth from 6 months - 2.5years, but that was mainly because a lot of people gave us disposables when he was first born. In the early days, yes it is a bit more work because of the mess and the number of nappies needing to be changed.
Here are some places in HK you can look at different varieties of reusable nappies:
Tots Bots cotton fitted nappies
Mothercare Lee Gardens 2
Mothercare reusable nappy system (like GDIAPERS)
Mothercare Lee Gardens 2, and LCX Harbour City TST, maybe other locations too
Fuzzibunz quick drying pocket nappies
Bumps 2 Babes, Pedder St Central
Fuzzibunz, Tots Bots, BumGenius, Happy Heinys, Bumkins
Online from Macau
www.doubibou.com (also run workshops)
Bambino Mio prefolds and covers
www.shopinhk.com (cheaper) and Eugene Club Centre, Queens Rd Central, MegaBox, Tsuen Wan Discovery Park
Normal flat cotton nappies & muslin nappies
Mothercare, all locations. Bumps 2 Babes
And another option, not in HK but close:
Bumwear one size pocket nappies
www.bumwear.com (Singapore)
The Gdiaper type systems are probably your most expensive option of any of them because you're paying not only for the costly setup, but then ongoing costs to buy the absorbent disposable pads.
The flat nappy system is the cheapest of all, because it's not that much to purchase flat cotton nappies and some cheap covers (can get cheap ones from Wing On etc, or more quality ones like Bambino Mio), but they are complicated to fold and more bulky than a shaped nappy.
For all of them, you shouldn't need to soak, just wash them (after getting rid of the solids into the toilet) on a thorough cycle in the machine. I do a cycle that includes a prewash and then a long wash cycle. They always came out fine.
You have to be aware though, that it is never going to be as completely easy as using disposables. You might sometimes get stains, might end up spending more money than you thought, might find problems with rashes. But then, people who consider making alternative choices like this don't make their decisions on what's 'easiest' but on what's best for baby, the environment, and your whole family, so you have to weigh it all up.
We have found that overall the reusable ones were better. When we had occasional issues with them, we just used disposables for a week or so till we got back on track.
