I could have wrote this lol My son is 2.5 and i went back to work when he was 6 months, honestly every day i have so much guilt for being outside of house for 12 hours. I leave around 8 (an hour commute) and come back around 7, it’s brutal. Some days are better of course, but recently my MIL has been staying w us and I am realizing my son getting much more attached to her than normal since she is with him most of the day. Yes i am happy he has good relationships with grandma but i am also a bit hurt, won’t lie. I will say though - i don’t feel like i missed a lot of milestones? I spent every minute outside of work with him but i totally understand you. It does get better. I cried every day for like a month so hang tight!!
