How do people survive going back to work?! Being up constantly throughout the night I only make it through the day because I get to nap with her in the mornings. When I go back to work I'll be going from 6-2 and I'm sure I'll have to get up around 4:30 to get her ready and feed her so my husband can take her to daycare. I'm already hating this and I haven't even started back yet 😰
