The 'No Doubt' star said that she has to arrange for making the trip comfortable for her baby.
"He's going to be in the tour bus.
We have got to figure that out,' Contactmusic quoted her, as saying.
She added that she would make sure that she rocks her son to sleep before she goes on stage to entertain thousands of her fans.
"I am going to bring my rocking chair and just rock him to sleep before I go on stage," she said.
Meanwhile the 37-year-old accepted that she is gnawed by the guilt of embarking on her 2006 solo tour with her newborn son, but she feels that it was his company that made her trip lively.
Stefani said that she knows that people wonder why she did not take a break after the birth of her son, and that like a typical Catholic girl, she too is feeling a bit at fault.
However she added that she made the tour because her newborn son was with her.
"I know people might look at me differently and wonder why I didn't take a year off. Well I am the original Catholic girl who has all those feelings of guilt too, but Kingston's here with me," she added.
