Laboratory testing of 18 pouches made by Ella's Kitchen, Heinz, Piccolo, Little Freddie, Aldi and Lidl found many to be low in vitamin C and iron, while some contained more sugar in a single pouch than a one-year-old should have in a day.

When we put this to the brands, the market leader Ella's Kitchen said it agreed with all three points.

Ella's Kitchen, for example, describes savoury products as "perfectly balanced for growing babies", while Piccolo claims many pouches are "packed with goodness".

Piccolo and Little Freddie told us their packaging accurately represented the key ingredients and flavours contained in their products, while Ella's Kitchen said it "would never use" misleading claims.

The highest found by the BBC was Ella's Kitchen's Bananas and Apples, which has 19.6g of sugar - equivalent to more than four teaspoons.
