When DS was born we used terry squares and there was no other option as we couldn't afford disposables. In the end we ended up using disposables as well terry squares just didn't cut it with a heavy wetting little boy.

Convincing DH to use modern cloth was a combination of costing and practicality. I had to do some serious research as to why these were going to work where the others failed. I also bought 1 to start with, to see what it looked like and told DH it was for taking photos in - so she wasn't in an ugly disposable in her newborn pics. Once I saw them and we saw how well they worked I bought a few more and then used the cash angle. Everytime I didn't spend $30 on a packet of disposables I got to buy a new nappy (about every week - week and a half)
