Hi

Are you still on maternity leave with the consent of your employer or have you stopped working??

If you are still on maternity leave, I would just say so in bracket somewhere on my cv. If you have STOPPED working, no need to say you are on maternity leave.

I don't think you need a career objective. I personally like a cv that is plain, simple with only the basics (personal details, schooling, degrees, work experiance and references - no more than 3 pages). So if you put down previous work experiance, for me, that would be sufficient.

Hope you get a job soon!!
