Can I temp at night?

I bed share with my LO which makes temping in the morning g tricky as we get up straight away at half 6. I have been getting her to sleep so laying down for an hour and then temping once she’s gone off. Is this a stupid idea? If I’m consistent doesn’t it not matter and I’ll still see the range / fluctuations necessary? I have ADHD and remembering to do things is not my forte but I’m doing well with this technique so wanted to check the experts before I continue on! First cycle temping :) thanks so much
