One of the major choices you need to make when cloth-diapering involves deciding whether to purchase diapers that fasten with snaps or Velcro (aka, hook & loop). They each have their benefits, which are listed here as I see them.
Easier/faster to fasten
More adjustable–you can fasten the velcro anywhere along the strip
closer to disposables, so daycare may prefer
Your child may be able to take the diaper off at inopportune moments
Velcro needs to be fastened in the laundry to prevent them from damaging diapers and attaching into one long chain of diapers
May not hold up as well over time
Don't need to fasten them before putting them in the laundry–can just toss the dirty ones in the pail
Will probably last longer–closures won't wear out
As your child gets older, he/she will not be able to unfasten the snaps independently as easily as Velcro
Big hands may have trouble reaching all of the snaps
You have a set number of adjustments in terms of size/fit
One last thought–I have seen vendors offer to change your diapers from Velcro to snap-closures and websites that offer do-it-yourself instructions. I have seen far less talk about changing from snap-closures to Velcro. I'm thinking that this means there are more people who come to prefer snaps at some point. It also means that you have the option to convert from Velcro to snaps, whereas it may be more difficult to go the other way. Grovia will convert for you for $3.50/diaper.
