It can be done..........my own kids were 10, 7, 4, and 18 months when I started college.
It wasn't easy, of course; even though I had plenty of help from my husband and sister, I still had to give up what was then a very active social life, resign from the community-service committees I was serving on, and put my nose to the grindstone for four solid years. To say the least, supportive family and/or friends are a MUST!
You also have to be prepared to take time just for yourself. Being a full-time student and a mom is tough, and you'll last longer---and do better---if you take a few hours each week to do something that's only for you, whether it be a massage, an afternoon out with 'the girls', a five-mile run, or whatever refreshes and energizes you. I say this because I
didn't do it, and by the time I finished nursing school I was burned-out and exhausted; as a result, I didn't choose my first job well, and I lived to regret it.
Good luck to you. I'm sure you'll get lots of good advice here.
