Pretty strange problem here - I give my 2 year old filtered water in his sippy cup, but it sometimes changes to a murky, yellow colour. Which seems to make my son hyper and won't sleep until 1am. I do check/clean/ change the water and cup when I can, I just don't understand what is turning the water yellow. To make things worse, a family member is blaming me for this and thinks that I am putting something in my son's water! (This family member is known to blame other people for things that aren't their fault) But I don't like being accused of something that I haven't done.
I would be greatful if someone could tell me what's going on.
You're saying you put clear water in and it mysteriously changes colour? Does the same happen in a different sippy cup? Have you tasted the yellow water? Does it only happen when family member is around?
Thankyou for everyone's help. It turns out that it was backwash from the foods he was having. (I gave him some carrot corn sticks, then checked the water later on, and found some food particles and the water has changed colour.) The family member who blamed me for it has been told and hasn't said anything else about the issue - but is stomping around like a bear with a site head.
