I’ve got a friend with a little boy who is 3. I’ve not known the girl long but she is very lovely and seems to care for her boy so much. However, I have noticed for the past month or so on a few occasions her little boy smelling of poo. I’ve gone to pick them up and he’s come out of the house smelling like it. We’ve been on days out when he’s started smelling but she doesn’t go and change him. I’ve spent a lot of time with her recently but have never seen her go to change him, he is also not potty trained so this doesn’t explain it. I don’t know if I should say something but I’m worried about upsetting her and ruining the friendship as she is lovely but the smell is very unpleasant, especially when all sitting in a car together, and I am worried about the boys well-being. Any advice appreciated
