I had prefolds with covers, BumGenius pocket diapers and bought gDiapers thinking they would be good for out and about. I hated the gDiapers! They were a huge mess when baby went poo. With my prefolds or bumgenius clean up was a breeze. And gDiapers are sized so you have to buy again each time baby grows out of their diapers. I think GroVia does come in one-size though.
If I had it to do over I'd go all one-size pocket diapers (like bumgenius or Thirsties) and call it a day! I take really good care of my diapers and I just had to replace the velcro on ours that are over 2 years old. But we only have a few (4) so if we had gone with all pockets they would last longer because you use them in rotation so the same diappies aren't getting used over and over. The newest version of BumGenius is designed to make refurbing them (changing velcro or elastic) super easy when the time comes.
You could also invest in a diaper sprayer to make clean up easier but if you breastfeed you don't even have to rinse the diapers. That comes once baby starts solids but then you get some biodegradable liners and it makes clean up a snap!
And get or make cloth wipes. I use them any day over the paper wipes. And it's another huge savings area.
Your hubby will get on board when he sees the savings! It is huge! I loved not feeling like I was running out to buy diapers constantly and literally throwing money in the trash can.
