I would schedule based on your support once you have your child. For me, I would have rather have done the more difficult classes pregnant and subjects that are easier for me once I had my child. For me, being pregnant was way easier than having a newborn (even with lots of help). The sleepless nights and constant nursing may make your studies harder. If you are good at memorizing take psych or anthro or something like that when you're a mom and save the more difficult studies (physio) for when you're pregnant. Just my 2 cents :) I took Anatomy, Chem and developmental psych with a 6 month old, and pumping all the time, lol and it wasn't so bad :) I couldn't imagine doing that load with her being smaller. Good luck!!
