Hi, I am a professional looking for some advice to support one of the families I am working with. They have a pre-verbal 5 year old who is fixated on playing with water. He frequently floods the house due to this. As soon as he arrives home from school, mum will make him a bath for him to have water play but he very quickly heightens and starts to run the taps which is then difficult for mum to be able to stop as he can become dysregulated by this. Mum has said that she cannot take him to her family or friends' houses as he has also flooded those in the past. He will climb onto kitchen surfaces to reach the kitchen sink. If it is raining, mum has also reported that he has previously opened windows (upstairs) so that he can get to the rain. He doesn't currently have the language to access things like social stories and isn't yet responding to visuals. Do any of you wonderful people have any suggestions for safe and controlled water play activities at home? Or alternative activities which mum could try which gives this same sensory input (if that is what is driving his fixation that is!)... Or any practical advice to share where you may have experienced this also? We are submitted early help for additional support at home as mum has recently had a baby and there has recently been a house move. However, mum reports that this fixation existed prior to all of the changes... Any ideas?
