If you've got kids you'll probably know how difficult it is to attempt to do the shopping while keeping them entertained and preventing any major tantrums; so now, Lidl is hoping to make shopping with little ones a bit easier by rolling out cute 'Fun Size Trolleys'.The teeny trolleys were available in a number of stores during a trial period and are now being rolled out across the UK, meaning children can help out their folks with the shopping or repeatedly ram into their ankles, depending on the type of kid that's pushing it. The mini trolleys will be set up in a special nine-trolley bay, and parents won't need to put money into them to make them work - unlike regular trolleys. Lidl is hoping that by introducing the small trolleys it will help children to become more involved in doing the food shop and thinking about healthy eating. Ryan McDonnell, commercial director of Lidl UK, said: "We're constantly looking for new ways to make shopping more fun and engaging for kids."We're keen to help parents build their children's understanding of what they eat, and we hope that our new Fun Size Trolleys will encourage kids to play a bigger part in the family shop."This isn't the first time Lidl has made big changes to how we shop, last year the supermarket announced it would be getting rid of black plastic from all its fruit and veg. Speaking at the time, McDonnell said: "This significant move away from black plastic demonstrates our dedication to tackling this important topic. We recognise the current challenge that black plastic presents to the recycling industry, which is why we have made it our priority to remove it from our fresh ranges."As part of our commitment to achieving our ambitious targets, we are continually exploring opportunities to cut our packaging, and where packaging is necessary to protect food and minimise food waste, we will ensure that it is reusable, refillable or recyclable."As well as removing the black plastic from its fruit and veg, the supermarket also promised to reduce plastic on its own brand products by 20 per cent by the year 2022. And by 2025 vows to have 100 per cent recyclable or reusable/refillable packaging on its own products while also increasing the recycled content of own-brand packaging to 50 per cent.
