I had kids whilst studying and I completely omit this when looking for a job. If the recruitment panel has three people, one surely thinks that it means you parental responsibilities might clash with the job because your child is still a baby. You interrupted the studies but didn't withdraw the course, you just stopped the clock for a year. I wouldn't consider it a gap. Put your starting date and expected graduation date. If someone asks why it might be taking you a year longer, you can say you had some extension due to family circumstances.
I would focus on showing skills that highlight that you are a team worker, reliable, organised, sociable, you pay attention to detail, meet deadlines, IT skills, etc. I therefore would mention things such as being part of sports clubs, book clubs, scouts/brownies, your best grades and how you achieved them, an example of a project that worked well, volunteering, web design, etc. Don't put your personal website if you just talk about parties, but mention it if you've helped a classmate to set up her own blog, for example. If you've done things such as lead a class group, or obtained a grant, an award, or were mentioned in the school newsletter, etc. If you have always submitted on time coursework (if you had extensions, this is still on time), what was the best feedback that you had: if it said it was well written, well structured or organised, or that you clearly have used extra sources for references, used the referencing guide appropriately, etc. That you take pride in your punctuality and have a very good record of attendance, whatever.
The important thing is to say ONLY what is relevant for that job. I used to put everything I did because I wanted a long CV, but unless it's for certain sectors, two pages maximum. Even if you can only put one or two jobs, describe in more detail what skills you acquired there, instead of adding non-relevant activities.
Something useful is to make a table with two columns. One with what they are asking, the job description or personal requirements. On the other column how you can prove you fit that requirement. If they ask for someone organised, you don't necessarily need to proof you have worked at timetabling people in an office, but can discuss how you liaised with all the classmates in your group assignment, made sure they submitted their parts on time, arrange a meeting to combine the different parts, set tasks for proofreading, discussed feedback for improving the final draft, etc.
I'd be happy to have a look at your CV (remove personal data and change companies' names if you want) and give you more specific advice.
