My baby is one and goes to nursery two days a week. In the past month he has come home three times with his skin covered in felt pen (see attached pic). The first time I didn't think much of it but now it's becoming regular occurrence and it's starting to grate. When I mentioned it politely his key worker just said they use pens in the baby room, she didn't seem bothered I was unimpressed. Clothes is one thing but I think on a baby's skin crosses a bit of a line. Has anyone experienced this? I want to ask then to stop using pens with him but DH thinks I should just wait and monitor the situation. I don't see why as bound to happen again. Any thoughts would be appreciated.
