My 4 year old DS was recently diagnosed with a chronic illness. Not life threatening but needs closely managed and means that he qualifies for disability allowance. This is quite a lot of money every month and as we are in the very fortunate position of not needing it to live, we will be putting it into an ISA for him every month. When he turns 18 this could be worth a lot of money. He has an older brother and sister who I can’t afford to put money away for like this and I’m worried that when the time comes for the ISA to be transferred into DS’s name, this will cause problems with jealousy and resentment. Has anyone ever been in a similar situation or have any advice or have any advice on how to minimise any bad feeling or favouritism?
