I would add something that is counterintuitive but unsurprising to people who have children: learning long/complicated words is actually not a problem at all. Kids love learning and saying long words with interesting sounds in them. Sometimes it’s even easier to learn long/complicated words because they are easier to distinguish from shorter words.

Ask any 4 year old whether they would rather say “Tyrannosaurus Rex” or “dino”.
