There's no way she's building her own production line. She's a middle-man/distributor with no employees. It would require buying a factory, machinery, hiring dozens of employees, and that's just the stuff I can think of off re top of my head.

I think other poster's are correct, if she does add production lines, it will be through additional orders to NADC and they will expand their own business.

There's also this: I hadn't heard or read that she was adding production lines, but I had read that she was expanding products like diaper wipes and creams. If that's the case, again, she wont be Doug that on her own, she'll be sourcing them from other manufacturers and distributing them with her private label (Mother's Touch) as she is the diapers.
