LadyIris, enjoy your birthday!
Karen, I learned the hard way on oldest DS that those "swimmers" don't hold water! Of course, that's the point....but we put him into his carseat dressed for swim

The alternative is the 40-pound diaper

which is really gross, but it is funny to watch the little one try to WALK with such a heavy diaper

Then you have to quickly change them before they tip over!
Lee, I am going to PM you with my email and we'll work out a plan.
I have done vinegar rinse and I just put it into the auto dispenser in my washer. I fill it about halfway with vinegar and then put water in for the rest. When I use fabric softener I fill it 1/3 softener and 2/3 water. I like using vinegar on my towels, since using fabric softener makes them less absorbent. So whenever I do a towel load I use vinegar. It also cleans out the softener dispenser at the same time.
Last night when my dad & his friend were visiting we had a very interesting conversation. His friend works in New York City in the financial world, but he & his family live a quite frugal lifestyle. I'm sure he must really feel in the minority in that respect, in his line of work.
