How do I request the same leniency without coming off as whiny?

How do I request the same leniency without coming off as whiny?

I have a hybrid schedule, which was perfectly fine until I became a mom. My commute is almost an hour each way. If I ask to work from home (other than my normal WFH days) because I’m under the weather or sleep deprived (young child), my manager expects me to make up my days in the office. If my WFH day is Thursdays and Fridays, and I WFH on Monday, I “forfeit” Thursday or Friday.

Here’s the kicker. My manager is allowed to work remotely weeks at a time in a different state several times a year (non-work related travel). I know of another person who recently had their job re-created to be remote when they decided to move out-of-state.

In summary, how do I navigate a hypocritical manager when it comes to WFH policy? I have witnessed first hand how some people can “be the exception to the rule.”
