My friend told me I should come to this site to ask for advice, since I still don't have too much knowledge on this stuff, and he doesn't really know what we should do to alleviate this problem. I don't want to act as his mummy or carer, and he doesn't really want me to be that either, I'm better suited to the role of big sister/older but not adult, but I haven't been able to get into the mindset to see him as 4, and until I can he wont be comfortable acting little around me.
