If your baby doesn't have a rash then you want to take the necessary measures to avoid one from developing. For my baby, it took a combination of products to finally reach bum happiness. We use Pampers Snugglers Diapers. These keep the dampness away from her skin and allow her bum to breath! Also, they don't leak and the blow-out incidents are drastically lower. The next most important ingredient are sensitive wipes. I use Huggies Natural Wipes because my baby's skin is too sensitive for scented products and the natural ones are unscented. Switching from regularly wipes to natural wipes made the biggest difference for my baby.
Next, I am very picky about lotions now. For the first year of my baby's life I used the lotions that had been given to me as baby gifts. Although these lotions were high-end brands, I noticed that my baby started getting bumps on her back and bum. I switched to an unscented lotion and the bumps went away! I use Aveeno unscented baby lotion and I love the results. No funny business, just baby soft skin! Last but not least, I quit using my normal baby wash because my baby's hair and skin started feeling dry. I went on a hunt for an awesome natural baby body and hair wash and I found one. Honest Company Shampoo and Body Wash. It is natural AND smells delicious!?! Once I added this beauty to our bath tub ledge I have to admit that I was tempted to start using it for my myself!
These products have saved my baby's keister (literally!!) and I hope they can save yours too.
