Yes it can be done, but it isn't easy and you do have to be realistic about what you can achieve in what kind of time frame. I went back when DS was 6 months and got PND from the pressure of everything. I ended up re-starting when he was 12 months but for me it was only achievable because DH was very hands on and essentially the primary caregiver, and worked around my timetable. It is very rewarding, but there would be no shame in waiting till after the house is finished (don't under estimate the time and stress of that as well). Having said that you can always apply and start and then drop out before the fee or census dates and then you would have had a taste of how much it would work. Good luck with whatever you decide
