My mom is an LPN (in the U.S.). She was a stay at home mom for 8 years. She went back to school in an ADN program when I was ~8 years old, and she didn't finish - she only had two semesters left, but she couldn't do it with an 8, 6, and 4 year old and very little help from my dad. (He's old-school, and believes that child-rearing is women's work.) So she left the program and was a SAHM again.
6-7 years later she went back to school! She finished her LPN program when I was in high school, around 16 or 17 years old. I'm 25 now, so she's been a nurse for almost 10 years, at the same hospital, in mother/baby. She's now trying to do an LPN-RN program. She's 50. She was so scared to try again, scared that she would have to drop out again or that she wouldn't be able to keep up with the work. But she worked really hard. I'm proud of my mom!
It's never too late and you are never too old. You can do it!
Now she DID say that it was easier to do when we were teenagers My youngest sister was 12, and we looked after each other, and I could cook dinner and clean up after ourselves when she went to her school and did her clinicals (mostly evening classes). That's how I learned to cook, taking over for my mom during nursing school, lol! We also studied and did homework all at the same time, lol. We were also older so we could give her more encouragement, too - "go mom! you can do it, you've wanted to be a nurse for years!" We really wanted her to be a nurse, as much as she wanted to be one, and she says the encouragement helped her keep going when it was hard.
