Karen, The unofficial record for lactational amenorrhea (no periods) is over 3 years. This mom was breastfeeding twins who were highly allergic to almost everything (given formula as preemies..)so she was providing a good deal of their nutrition. I have heard moms go much more than one year nursing one child. There is a wide range of normal here. As long as there are no untoward symptoms, mom should relax and enjoy.
