Working moms of newborns and infants

Hey ladies, I’m heading back to work from maternity leave in about a month when my son is just over 3 months old. I work from home about half the time, but a lot of moms have told me I won’t be able to work and keep him home with me during the day unless I hire a sitter. I’m worried that I won’t be able to spend much time with my baby after I go back to work and put him in daycare, especially the days I have to go into the office because the commute is nearly an hour each way (I live in Atlanta where traffic is awful). How do you maximize the time you spend with your children as a working mom? And how do you deal with the guilt of feeling like you’re not doing enough for them because you have to work? Any advice will be appreciated! 😊
