Unfortunately, people like the OP are the ones who give BLW its wanky reputation.
BLW is supposed to be a way to get children eating 'normal' food in a 'normal' way very quickly.
Rather than starting with puréed veggies, then adding meat and fish and then slightly lumpier purées, then adding in a bit of finger food, then around age 1 allowing egg whites and strawberries etc etc, BLW is a way of showing children how to eat what everyone else is eating from six months. So, yes, they use their fingers and yes it is messy, but the whole point is to get children accustomed to a 'normal' way of eating from the get go.
So, sticks of crudités, batons of roasted veg, layers of lasagne, hearty meat stews etc. are all available for the baby to try. The theory which did not work at all with my DD1, but has worked with DD2 is that they eat properly, choosing what they want, using their hands to eat, rather than being spoon-fed (literally) which can be time consuming for the parents. They learn about appetite, stopping when they are full, different tastes abd textures (rather than all purées).....
You either buy into it or not, but I am baffled as to the OP's idea that spreading strangely themed food out of a storybook all over the floor and letting babies and toddlers go wild (smooshing??) with it forms any part of BLW.
