The new products, available from this month, will extend the range to eight offerings.
Newcomer Truly Fruit Bar comes in two flavours, apple and plum, and is joined by Multi-Cereal & Milk Bar. Both are aimed at enabling youngsters to feed themselves.
All three products, suitable for children from 12 months onwards, are priced at 39p each.
