I started using reusable nappies a year ago when DS1 was approaching 2 and I was pg. I still have 2 in nappies and find them convenient. When I'm out, they go in a lined wetbag along with the reusable wipes. I still use some disposables, but using reusables a minumum of 75% of the time makes a massive difference to our bin capacity and little difference to the amount of laundry generated by the family. I have no problems with smell despite DS1's legendary digestive output from his food allergies/ intolerences (nursery staff shudder at the memories). If a residual odour does build up, a couple of days on the washing line in any weather works wonders. DS2's milk poo is guarenteed to blast through a disposable nappy into his clothes, so I'm still washing an item everytime he poos, and it's easier to change the nappy only, than strip his outfit and lug extra spare clothes. I've had very few poo leaks from reusables. DS1 leaks much less in them too as they're better sealed against it oozing up his back. I wish I'd got into it sooner.
Reusable wipes are totally awesome. It used to take 12+ disposables to deal with a dirty nappy change. I'd fill up a flimsy nappy bag at least with the wipes alone. I normally saved the bother and showered him which could be 2 or 3 times a day at his worst. Even a stonker can be done in 4 reusable wipes. DS2 is still mainly milk poo and is done in one wipe or two. The cotton flannel is much better at foody hands and faces as the gunk grips on. I've not bought disposable wipes in over a year.
Reusable breast pads have saved a fortune. Bamboo ones are very absorbant and have are much more comfortable than plastic backed ones which I found sweaty in the warmer weather. They also don't screw up in your bra, and I no longer find manky used breastpads festering in the bottom of the changing bag as they go in the wetbag.
I'm going to try CSP when the need arises. I haven't had the need since learning of its existance. Hopefully it won't have that horrid chaffing feeling that I get from disposable pads.
Oh and reusable nappies are very funky and pretty, and they have resale value when I've finished using them. Now I'm finished with the smaller ones, I'm going to lend them to an interested friend to try. I also need less nappies in the changing bag as both boys wear the same size with the nappies being adjustable, rather than two sets of sized disposables.
Reusable products won't work for everyone all of the time, but part time use still makes a positive difference. I find them convenient enough, and the function and practicality is quite different to what many people imagine. My thoughts on nappies when pg with DS1 were totally out of date!
