She should be fine love, but it always up to you. I work in a nursery and we have 1 yrolds who still use these
My 3 year old still chews his sometimes he's never broken it
Safe to use but if your anxious I'd remove it
My son love these and we haven’t had any issues x
I mean… I have seen little teeth chewing away their cot… I wouldn’t think it impossible. So think it’s good you took it off them
