Moms who work full time - does it ever get easier?

I'm on day 4 back to work and I still cry every morning as I walk out the door. My mom is watching my baby at my house and I am SO grateful for that, but I miss her like crazy every day. My heart actually hurts...like I feel pressure in my chest when I leave her. I've cried a couple times at work too (in private) because it's so painful being away from my baby. This is such a fleeting/special time and they grow so fast, and I feel like I am missing so much precious time with her.

How do all you full-time working mamas do it? 😔
