my son who is going through tests for PDA/ASD/ADHD has had a imaginary friend called the naughty elf who gets the blame for everything. this elf arrived when my son was just over 3 and doctors said he would grow out of it however my son is nearly 7 and the elf is still here in fact only this evening my son told me the elf told him to throw his dinner on the floor.any advice welcomed!!!
