Re: ds has diarrhea and a rash....help
Have you tried "Triple Paste"? You can buy it at Walgreens, but you may have to ask the pharmacist to get it from behind the counter. You need to put a good paste on the bum and it should work. Whenever my daughter starts to get one (especially with antibiotics) I put this stuff on and after awhile I notice a huge difference. I usually throw a small washcloth down as a liner in the diaper so it doesn't stain. Good luck!
BTW my daughter had tubes put in a couple weeks ago and she is a totally different toddler! Her vocabulary has skyrockted, her balance is great, and she is so much happier! (Almost a different baby)
