Going back to work tomorrow…

My maternity leave has officially ended and I’m returning to my teaching job tomorrow. I’ve asked my teammates to pretend I was never gone and not ask about my baby because I know I will become emotional. I’ve spent basically my entire mat leave anticipating this day :/ Luckily my MIL is watching my 12 week old for a few weeks and then my mom will take another two weeks before ultimately sending him to daycare. Also, thankfully, my school is only a few minutes from my house, so I won’t have a long commute. I’m just sooo sad to be leaving my own kid to spend the day with other people’s kids. I’m also worried about bringing germs home. Any words of wisdom or stories to make me feel better would be so appreciated!
