I am doing postgrad part part time (ie one unit of coursework at the moment) with an 9 month old and it is VERY hard going. Like someone said it is the headspace of engaging with something other than baby. It does change verything. I find it very difficult to focus on articles and readings even when DD is asleep and at night time I am so exhausted I couldn't care less about uni work. There was no chance of me doing anything when DD was earlier than this as she was/is a 24hr job. You need long periods of uninterrupted time especially with research to get into it and for me it is not possible to do properly with a young baby as you do not get long periods of time nor have the energy or motivation due to tiredness. I also feel that I owe it to my daughter to give her all of my energy at this point in her life.
