Back to Work

Seeking advice on going back to work after maternity leave. I’m so sad just thinking about leaving my baby. I just want to spend every second I can with her. I will be working 4 days a week and she will be watched by her grandparents. I find myself being jealous of them already, they will get special quality time with my baby while I’m working my butt off and missing her all day. Any words of wisdom would be appreciated, I wanna approach this with the best mindset I can but I’m having a hard time already.
