The easiest to use BY FAR are the all in ones (AIOs) because they are most like disposables. However, the primary downfall to all of these diapers is the drying time. In comparison to pocket diapers and covers with prefolds/inserts, they take forever.
At the moment, we have one Bumgenius Freetime, three Swaddlebees Simplex AIO OS, and three Bumkins AIO OS. We chose one size diapers because they will fit the little one now through potty training. I just didn't see the point of buying sized diapers that we would have to keep replacing as the little one continued to grow.
The Bumgenius Freetime has the fastest drying time but, I think the over all design is strange. It works well right now since little one is small but, when he gets bigger I'm not sure how absorbent it will be. The other down side to these diapers, while petty, is that they come in primarily solid colors. (I enjoy prints.) Bumgenius Freetime is now available on Babiesrus.com which means, all those gift cards we received as gifts when Charlie was born can now be used for cloth diapers other than gdiapers or Bumgenius 4.0. We haven't tried to Bumgenius Elementals yet but, we will be trying them in the next few weeks.
The Swaddlebees Simplex AIO OS TAKES FOREVER TO DRY! But, they are super absorbent and come in the most adorable patterns! They are more expensive then the other two types of AIOs that we've tried but, I like them the best.
The Bumkins AIO OS are the cheapest of the three and I feel like they aren't as absorbent as the other two. This was super disappointing because I LOVE their diaper covers. Bumkins has really cute patterns (like Dr. Seuss) but, it just isn't practical to have a minimally absorbent diaper. I will keep trying them but, right now I would gladly trade them for three new diaper covers. The good news is I got them pretty much just for shipping with a Plum District deal. (I have to thank my readers who also bought the deal using my link because I was able to get the deal for free!!)
