Juggling parenthood, school and work

Ichigo • I have one daughter. I'm also pregnant with my second. Unmarried.
So today was the first day of class for my school (chestnut hill) and I already started off bad. I was 20 minutes late, had no school supplies and am still 3000 in debt to the school. And this morning I didn't have enough wipes diapers or clothes to bring her to daycare. So yea, terrible planning on my end. So I was hoping for tips from peoples who have been through this or something similar
