January Jones became a mother at the ''right age'' in her life.

The 34-year-old actress - who plays Betty Francis in 'Mad Men' - is having ''so much fun'' with her six-month-old son Xander and notes he has changed her priorities to be excited about ''cosy T-shirts'' rather than pairs of high heels.

She said: ''I am at the right age, the right time in my life, where having him is just so much fun. I feel very lucky, I think being a mother is something I was meant to do.

''There's less glamour in my life though, now that I am a mother. I get more excited about cosy T-shirts than about an amazing pair of heels. That is sad. But your priorities just change.''

The blonde beauty can't imagine being without Xander - who's father she hasn't revealed - so takes him to work with her and cuddles him at every possible opportunity.

She added to Britain's Grazia magazine: ''I'm lucky I have a job where I can bring him to work, so I was still able to nurse him, and I could run over to see him and Squeeze him when I missed him, which was often. I can't imagine having to be away from him.''
