Hello, my daughter of 7.5 months ate a piece (2 cm) of rubber children's mat while I was cooking porridge for her. As I was alone with her, it was impossible to constantly watch her. She somehow managed to pull out this mat... I am so tired, I have no strength left, just ???. What could be the consequences? Should we go to the doctor?
