For gluten-free, citrus-free and tomato-free Kerry Clayton, shopping and cooking is a challenge.
As well as her own food requirements, her 10-year-old son is dairy and wheat-free.
The family shops at multiple stores each week to get the best free-from options, cooks adaptable meals like jacket potatoes and pasta, and makes cakes and cookies from scratch.
She spends about an hour a week baking, on top of running two online jewellery businesses and parenting another child.
When M&S launched its Only range in March, with products featuring six or fewer ingredients, Ms Clayton described it as "a dream".
