We don't have any kids yet, but I'm looking into options for when we do, and cloth diapering is one of those options.

I was babysitting my cousin's baby last week who uses cloth diapers. She used to use them exclusively, but now sometimes they put her in disposables because when she gets wet sometimes she leaks through the diaper and her onsie/pants get wet. Is there any way to prevent this with cloth diapers or does it come with the territory when they're sort of "in between" sizes/snaps?? (they use the snappy kind with the insert, not sure of the brand)

Also, as an amateur cloth diaper-er, I had a hard time telling if she was actually wet or not to decide if she needed a change. I ended up just wiping the inside of the diaper with my hand to feel it because I really couldn't tell. Is that typical?

I think i'm leaning toward disposable diapers for the convenience factor, but the cost factor of the cloth diapers is VERY appealing.
