Temp times?

I’m new to tracking. And I’ve been trying very hard to temp at the same times every morning. But the problem is, my daughter still wakes up sometimes at night. And it’s usually less than 3hrs before we’re up for the day. My question is:

Would it be ok to temp when she wakes up in the middle of the night? I’ve usually got at least 4hrs of sleep by then. But the times of night vary. I just don’t know if temping when i wake up for the day would be accurate.

THANK YOU
