It is hard, but possible to handle studying and taking care of your kid. Just try to maximize the efficiency of your studies. Try to get the best scores out of the least time. I am not sure what program you are studying, but if you are in an undergraduate program, just finish the assignments, read the lecture notes, you can get good marks without working really hard. This way, you can still spend a lot of quality time with your kid. I have quite a few colleagues who have little kids at home, yet able to manage work and family very well. Just be positive. Do not use "oh, I have to take care of my kid so I do not have time to study, blah blah blah" as an excuse.
