Amen to step three!!
Yes I've stated the same thing many times. Keep yourself Hydrated

and not with Soda,Coffee,sport drinks, etc. WATER is best it's so easy to just go and slug some water down every few hours during the day and often you can do it for free
I can honestly say that I rarely have to deal with the odor issue. And I also rarely deal with rashes. I know I've stated this before. But when I got away from Soda fast/Junk food Coffee and so on. Started drinking plenty of water. I never take anything for odor. Rashes became a thing of the past. Well OK I still get them in July and August during the hot months. But it's not usually that bad.
One thing that will also help with stopping/controlling Rashes and Odor is to keep yourself clean as well. Wipe your Diaper area down when you change can also help.
