January Jones admits being a working mother is “hard”.

The ‘Mad Men’ actress – who has not disclosed the father of her 10-month-old son Xander – felt “lucky” to be able to take her little boy to work with her but she found it tough at times because her hours were so long.

She told website mom.me: “I had to go back to work when Xander was six or seven weeks old, but I’m lucky that I have a job that I can bring him with me. I was able to bring him to work and nurse, and I could see him when I missed him, which was often even though I was only feet away.

“‘Mad Men’ has such long hours, and then you go home and you don’t sleep. So it was hard.”

However, January thinks going to work made her a “better mother” and she doesn’t think people should be judged harshly for returning to their careers while their children are young.

She added: “I think that as hard as it is, that if you have something that you love outside of being a mother, you should definitely maintain it, because it makes you a better mother.

“I think in America we are often judged [for going back to work], but I think we should always remember that it’s OK. It doesn’t mean that you are a bad mom.”
