It is so hard to say definitively as it depends on the child, and the support you have. 'Easy' baby = no problem. Partner who is helpful and hands on = great. Family around to help with babysitting etc = sure. If you don't have those though, it could be a struggle.

I studied with DD1 as a newborn, I was halfway through my course and dropped to part time when she was born which was, thankfully during the uni break so timing was on my side there. She started coming with me to Uni from 8 weeks as she was still fully breast fed and uni was all day so I wasn't able to leave her with anyone. She was a pretty 'easy' baby though and was very quiet and content, happy to just be with me, self settled beautifully from the start and slept reasonable amounts during the day and at night. The first 6 months was a breeze. I found it became difficult if not impossible around the time DD turned 6 months as she began to want to move around more, made a lot more noise and needed more attention. There was no way I could continue taking her with me to class or keep up with her demands during the day as well as get study done so I had to put the study aside. Secondly, at about the 6 month mark DD's sleep began to decline and I don't think I could have managed any study with that added stress.

DD2 was a completely different baby and slept quite poorly from the start. If she had been my first, there is no way I could have managed study.
