Did anyone go through a nursing program with children (what age would be the best)?

I have a 6 month old son and just finished my last pre-req to go forward with a nursing program. I wanted to be a nurse well before I even met his father and have been working toward this for a while! My last semester was horrible and extremely stressful. I am soooo scared to take this next step. My son's father isn't as supportive as I would like, as he thinks that I should be home with the kids until they don't need me as much (more independent). Although the whole time I was pregnant and taking classes (as well as once he was born), the rest of my family kept telling me they wanted to help, but I didn't get much. I say this because these people are the only support system I have in the area. My mother in law is VERY helpful, but she is retired and I don't think she should be watching my son ALL the time (she gets tired easily). My husband does not support day care and will not pay for it.
Ok, there is some back ground. My concern is that I really don't want to leave my son right now, but on the other hand I have been working so hard to get to this point. I finished EVERY pre req before hand so I could concentrate solely on the program. I guess my question is if you had it all to do over again, would you have been changed when you went through an RN program? Would you do it while they are under 2, wait until 4.....wait until 10? I want to do it, but I also know my limits and I think I would be so stressed that this may not be the right time.

Thanks all!
