Another person who hasn’t ever had a real life 3 year old and doesn’t know why “three-nager” is a thing or even what developmental milestones are for 3 year olds. 3 year olds aren’t even expected to follow multistage instructions. Like it’s not a thing any doctor would be worried about if your kid couldn’t at 3. That’s how uncommon it is for a 3 year old to follow instructions.
