Late developer is an expression used to describe a kid whose mental abilitty matures later than *that of* most children.

Is the *that of * part omitable, other replacements?


Thanks

You need the that to make it plain that you are talking about mental ability and not all around maturity.

[missdaredevil]

What does the *that* mean, in that case?

Thanks

It means, the mental ability.
