DS turned 4 today.
He's on the pathway for an autism diagnosis and has major sensory issues with his feet and, especially, his hands.
DF knows this and yet bought him slime for his birthday. Not only is it marked for 6+ but DS won't touch it - and if he did get any on his hands it would lead to a major meltdown.
It's not the first time DF had bought age/condition-inappropriate gifts - he got him Guess Who last year - for a child who is severely verbally delayed - and a drone at Christmas.
It all just feels a bit like he's buying for the grandchild he wishes he had rather than the one he's got.
DS is very bright and loves mechanical things/things he can build but DF ignores this when choosing gifts.
