January Jones finds it "difficult to be a working mum" at times.

The 34-year-old Mad Men actress cares for her seven-month-old son Xander Dane on her own.

January has a very busy professional schedule and returned to filming almost immediately after giving birth.

Although her diary was packed, January managed to squeeze in quality time with her boy whenever she could.

"I was back when the baby was only six or seven weeks old so it was difficult," January told Us Weekly. "It was difficult to be a working mum and just juggling all of that. But everyone made it work and it was great."

January and her brand new baby received a lot of love from the Mad Men cast and crew. They continue to support her and Xander on set.

"They made it baby friendly for me, because I'm the first female on set to have a baby so I got to bring him," she said. "He had his own room and I was able to work around it because I was nursing."

Although caring for the baby is strenuous at times January believes that all of the hard work is well worth the effort.

"He is eating solids and he is just jabbering away. He's becoming more of a little person. He is quite a charmer!" she shared. "I love to make him laugh. He thinks I'm funny and that's always a nice feeling."
