We used all the same brand last time, but that was near 6 years ago, and there were not all the different types available that there is now. I tried a few samples of others that were coming on the market towards the end of our DS nappy days, and they seemed fine, but what we had been using had been fine too.
This time we are using some BBH and some flats with ties (Disana) for easy dry time since the BBH can take a while. And I will be attempting to make a few myself to help save a bit of cash. Though this does require the initial outlay of suitable materials etc and time researching patterns etc, plus having your own machine.
I looked at BBH and liked the look of them, compared them with the ones we had had for DS (since sold them before we knew we were expecting) and thought they would be good. We have not trialed them yet, but Im sure they will be good, as the old ones we used last time were, and the BBH design looks an improvement on that.
I`d rather just get one that works and stick with it myself, if its a reliable brand why take more time and money getting samples of others? - unless you enjoy doing things that way, which some people do.
