My husband is 19 years older than me - hence my rush, too. He will already be 47 when we start trying for a baby in 16 months. Everyone in his family starts having kids late, his brother-in-law and eldest sister were 50 and 47 respectively when they had their first (and only) child. So, he's not opposed to waiting a little longer, thank goodness.
My MSN program is pretty much all on campus, and the first 15 months are just the same as any other accelerated RN program - classes, clinicals, etc. The MSN portion, involves clinicals and normal graduate level classes, too, but is referred to as non-clinical because you do not become a nurse practitioner, but a nurse educator. During the last year of my program (which is the second year) I will have more flexibility. We are allowed to go part time or full time, and you are allowed to take a semester off if you want to. So if, god forbid, it is a hard pregnancy or something else happens, I will be able to take some time off. I hope I don't need to, but having that flexibility is very comforting.
I have weighed the pro's and con's and for us it is the best way to go about things. I am not willing to wait several more years to pursue my dream of going to school for nursing (and having all of my pre req's start to expire), and I also want to have a baby while my husband is able to play with him/her, teach them sports, and just be active. He is in phenomenal shape now and no one believes how old he really is, but eventually he will age and creating a family sooner than later is worth it to me.
Sorry for another super long post! I guess it's obvious I have thought a lot about this. :imbar
