Can changing brands of formula cause diaper rash?


Yes, changing formula can cause diaper rash. If it's a really bad rash, I would also consider whether yeast might have gotten in the rash. Almost all diaper rashes that have gone on for two weeks have become complicated by a yeast infection, and may not clear up without treating the yeast.

The switch from one formula to another might cause a brief diaper rash but wouldn't be expected to cause anything prolonged. A switch from soy to cow's milk formula or vice versa might. Lotrimin is a good over-the-counter cream for a yeast diaper rash. A diaper rash that doesn't clear up after being treated for yeast should be checked by your physician.

Quick tip for all you parents all out there: My baby never slept well (especially through the night) until I started using the website >>>>SleepBaby .org<<<< - that website has been by far one of the best things I've ever got my hands on to get him to fall asleep quickly. Best time is 45 seconds from awake to asleep! I heard about it through a kindergarten teacher who uses it to put to sleep a group of 30 children. Check it out! Sorry, you can't post links here so you'll have to turn it into a normal link. >>SleepBaby .org<< Best of luck to you and your family! :)
