Re Eval my job after maternity leave

So I worked on a busy tele step down unit for over a year. I never really liked it but had my moments. I just had my second child and tried to go back perdiem nights. Well it's not working out. I thought I liked nights untill I went out on leave n realized just how hard it was on my body. I went back one night n felt horrible, plus lo was up crying! I got a few phone calls from a stressed hubby and a screaming baby. I really feel like I need some tome to think about what I want. I'm not sure I even like bedside nursing! Would it be career ending to stop stay at home n figure where n how to continue nursing?
