used to

[jennie77]

I know that "Used to" is used when people say something that happened in a particular past and no longer happens in the present.

But what about this sentence?

Recently I'd noticed that my kids weren't as well-behaved as they used to be.

In this sentence, the tense is already past. Then, "used to" is used to mean that the kis had been well-behaved before.

Do we use "used to" like this - rather than "used to have been", or something like that?

Thanks in advance~!!

The above is a contraction of, "Recently I'd noticed that my kids weren't as well-behaved as they used to be well-behaved."

Thanks Temico

But I'm fully aware that "used to" is contraction in this sentence.

What I am wondering about is about "tense" in this sentence.
"used to" means 'past tense', meaning " something happened before, but it doesn't now".

Recently I'd noticed that my kids weren't as well-behaved as they used to be.

The main tense of the above sentence is already "past".
So what I'd like to know about is whether we can used "used to" with "Past Participle", meaning "it had happened in the far past, but it stopped happening in the past."

Thanks again~

You can't use "Recently I'd noticed" because this action did not precede the kids misbehaviour. Re-write: Recently I noticed that my kids weren't as well-behaved as they used to be.
It is OK to say "used to" because that happened in the far past. The fact that they were not well-behaved recently and that you noticed it recently does not make any difference to what happened a long time ago.
