My LO is due June 4th. I plan on nursing for a year same as last time, but I’m also considering going back to school. If I enrolled classes begin the beginning of August. Keep in mind I still have a toddler and a elementary aged child at home. I really wanna pursue my goals but I feel like if I took this in right now I’d be setting myself up for major stress and massive failure. Anyone go back to school with 2 under 2? How did you deal? Online is not an option for me.
