Ben's Sensory Interactive Floor

Ben has a rare syndrome called Bohring-Opitz syndrome. He is turning 5 in Aug but has the development age of approx 6months to 1yr. He is unable to communicate, sit, walk or do anything for himself. He's been working really hard at school with cause and effect games and his communication through touch and eye pointing is coming on amazingly. Communication is a massive thing we struggle with with Ben, him being unable to tell us when he's in pain or when he wants something can be heartbreaking. We are looking to buy him an interactive floor which will help him work on cause and effect which will massively help him at school and home to communicate. These pieces of equipment are extremely expensive so I'm looking into a few ways or raising some money towards one. If anyone has any questions on Ben's needs or would like to donate we would be forever greatful xx
