Don’t panic, and remember that communication is key. Every parent is placed under a different set of physical and mental demands – whether that be sleep deprivation or the need to coordinate schedules with a partner or carer.
It is likely that your colleagues are either also parents or have experience with parenting through other people close to them. If your work life needs to adjust to make way for the demands of parenting, I would encourage you to identify the challenges, think of workable solutions, and speak to those you work with to execute those solutions.
I always prefer to give people the benefit of the doubt, hoping that my challenges will be met with empathy and understanding. If not, then perhaps it’s time to re-evaluate those you give your energies to.
