I remember my first week, studied at least four hours every night. It comes in spurts, care plans
were the worst, they could take three to four hours every night(had the instructor from hell).
My programme ran year round so at times child care was a real issue. Clinicals also had challenges, daycares open at 0700 and close at 1800. Well, it was expensive but I managed to find a daycare worker who would be there at 0600 for me to drop the crew off. Managed to do evenings and nights by the sheer grace and goodwill of friends. Husbands job required him to be overseas during those months.
Don't count on the goodwill of instructors, they are there to be educators not shoulders to cry on. Several of hours told us straight up the first week, your childcare is your responsiblity, if you can't arrange for 24 hour availability its time to rethink being here....
So good luck, and if it does overwhelm you, thats all right. There is a time and a season for everything, its just getting the lineup right. Your children are only young once and nursing school
will always be there.
