Help towards a sensory room for a unique little boy

Alfie is a lively little boy with a rare chromosome disorder 16.11p multiplication he is 6 years old has learning difficulties and cannot communicate. Without a voice life can be very frustrating, Alfie is a sensory seeker and part of his difficulties include sensory processing disorder he is always looking to fulfill his sensory needs he loves water therapy (hydrotheraphy) the most, aswell as fibre optic lights and bubbles which seem to calm him down massively when his emotions become too much. He is also currently getting assessed for autism and adhd also which is linked with this unique genetic condition, there can be many a meltdown and very challenging behaviour and we are looking for help to create a calming environment within the home a place that makes Alfie feel calmer and his sensory needs met too. I would spend the money on various sensory items which would also include a hydro pool.... and aroom creating a lightshow, bubble tube, calming music soft furnishings a happy place Alfie feels safe. Getting such therapies on local trips can make a massive difference on how Alfie feels, he comes back so happy and I would love to be able to provide that care whenever needed and a place Alfie feels relaxed, sometimes such meltdowns can result in injury to himself and people taking care of him and can be really difficult to control. Even the smallest of things can make the biggest difference. Thank you for taking the time to read. :)
