When Isabelle was born, it became clear very quickly that she wasn’t going to be one of those easy peasy throw-anything-at-em-they’ll-handle-it babies. No, she absolutely was not.

She was (still is) extremely prone to eczema, dairy made her sick, our washing powder made her itch and so, in those early days when we were figuring out her various allergies, we played it safe and only used water with cotton wool when changing her nappy.
