2 under 2 in school: thoughts + advise!

My husband and I have an (almost) 8 month old baby girl and we really want a second to complete our family, however, I’m scared that baby #2 is going to be too much to handle. I’m starting nursing school next fall (Fall 2021) and it’s going to be a lot, I know, but it’s “do it now” or wait several years and postpone getting a job right after graduation. Plus, if we wait, the babies would be over four years apart and we want them closer in age. Thoughts? Suggestions? Word of encouragement? xoxo
