I agree with the above, if you can time and money wise do the RN I'd say go for it in case later down the line you wanted to do the BSN and go for management but its really up to you. I work in Postpartum/couplet care and work with some great and wonderful LPN's and RN's and we all do pretty much the same things however the LPN's do have some restrictions like certain meds, pushing things, etc. I know it frustrates them b/c they have to depend on someone else to get something done.
The other reason I suggest it is b/c there were several LPN's in my nursing courses going back for RN and I work with some LPN's going for RN. So I think in some ways if you can it might save time in the long run. But it definitely depends on your time and money situation.
I have a two and a half year old, I got pregnant mid-nursing school and took a semester off then went back to school. I worked full time up until then also. Daycare was hard to do but if you go back to work as a nurse, you may end up using daycare then, and like posted above, my son really does enjoy his time at daycare. I did an evening/weekend program which was very helpful for working

Good luck either way, LPN's and RN's are both great!
