I went back to study when my DD was 8 weeks old which meant taking her to uni with me. I was really lucky to have a very supportive university where they allowed me to have her with me in all classes.

It worked really well for me as my DD was a really settled contented baby and allowed me to study and keep working one day from home for the first 6 months.

It really all depends on what your little one is like and how helpful your other half is. This is something that is difficult to predict. (I thought my DH would be a help but he was so taken up with his own work I was pretty much on my own, and I thought DD would be much more difficult to manage than she turned out to be!) Can you perhaps begin study and if it gets too much pull out/defer before you are forced to pay for the course? I know you usually have a month or so grace with most higher ed.

FWIW, I didn't go on to do semester 2 with DD and I am so glad I didn't, it would never have worked. She became much more demanding of attention at 7-8 months, rather than being happy to sit and watch me while I worked. Also, her sleep started to go down hill at the 6-7 month mark after being a good sleeper in the first months. Plus, I really wanted to play with her more as she got older too!

Hope that helps rather than confuses more!
