parttimediaperfree.com - Elimination communication - reduce the number of diapers you use by learning your baby's signals. I learned about this a while back, but we are just now going to actually start to actively try it (I did catch Jimmy twice a few months ago and we made it to the toilet! But then he decided he didn't want to sit on the big scary toilet, so I guess its time to get him a little potty chair lol)
