She seems ok now, a bit shaken but fine. I was feeding the baby in bed and she was messing about in my en-suite (not as fancy as it sounds!). Anyway, the upshot is, she ate around a fifth of a tube of toothpaste, then vomited a minty, foamy, mess all over my bedroom floor.
I have treated this with a dose of cbeebies, a cuddle and a fruit shoot. Am I right to not be too worried?
