S.H.
I did extended breastfeeding with my eldest... and let her self wean.
My eldest child self weaned at about 2.5 years old, my youngest child, my son, weaned at about by 1 year old (so this wasn't very long), but I did let him wean himself, I did not stop him.
For me, I breastfed after they woke up in the morning, before "solids", before naps, after naps, before bed, during the night IF they were "truly" hungry, and when they woke.
My Pediatrician, was very supportive that breastmilk was still prominent in their daily nutritional routine. MANY child development experts support extended breastfeeding. So don't get discouraged. My Hubby was also very supportive of extended breastfeeding our children, and in fact was very proud of the fact I believed in this.
For me, with my eldest child, I direct nursed throughout, no bottles. For my son, I used bottles and breast.
Throughout this, they MAY bite... but it stops. You just tell them "NO" and take it out of their mouth. They will learn. A baby will self-wean when they are ready. Each baby varies.
If you want to do extended breastfeeding... keep in mind that if you nurse AFTER solids... this is done to "wean" from breast... it makes them full and thus, they intake less breast afterward. And your breastmilk output will adjust. For me, I nursed BEFORE solids. *For the 1st year of life... breastmilk/formula is the PRIMARY source of nutrition for a baby.
As they get older, the frequency of nursings will naturally lessen. That is what happened in my case at least.
Good luck and no matter what, do what you feel is best...
