As a result of his crying at night, we did not have enough sleep.

As originally written (not said!), your sentences were a bit awkward and redundant.

Be sure to put a space after your puncutation. The above conveys the same thoughts, but in a more direct manner. I hope this helps! J.

Hi Satomi - It might have been better to ask this question in "Answers".

"I recently stopped breastfeeding my son, so he cries at night. Thanks to this, we didn't get enough sleep last night."

You don't need to begin each sentence on a new line.
