I'm not sure if I'm being a bit paranoid here but what's people's thoughts on a 4 year old having chewing gum?Personally it gives me the fear. I'm the same with lollipops.
My 4 yo DSD's mum gives her chewing gum. Her DF and I refuse to buy her it, he hates the idea of her having it too. Last night her 16yo brother gave her some. I felt that I couldn't really say anything as her mother allows it but the whole time she's sitting chewing it my heart was in my mouth. She then started rolling around on the floor and at that point I asked her to sit up when she has gum or spit it out of she's going to be rolling around.
My DH wasn't home at the time. I think if he was there he could have told his DS not to give her it but I felt that I didn't have the authority to do that as it would be undermining their mother.
