I have a 13 1/2 month old. We went on a trip to a waterpark Tues and Wed with his older half siblings. Yesterday (Thurs ) he had a blow out stool with a very pale yellow (grey poupon consistency) his back and out the sides of his diaper. I haven't had this since before he started solids! I chalked it up to a one time thing.... Then this morning I had another more yellow but still light and very soft stool (still grey poupon consistency), another one after that but it wasn't as large of an amount but more yellow (more mustard like). And now still another diaper that is more mustard color but still more watery like the second diaper.
He drinks water when not breastfeeding and once in a while juice with breakfast. Diet was not different on Tues or Wed and only drank either water or breastmilk.
Any ideas on what might be causing this? I thought perhaps the change in drinking water? Or perhaps he got some of the pool water in his mouth? He seems fine and acting normal otherwise than he had some irritation on his penis and it was red and painful when I went to clean it but I think it is due to the water chaffing on the swim diaper and the life jacket strap because baby powder is helping to reduce the irriation. Looking for some help please!!!! Haven't had diapers like this in about 6 months or more!!
