I agree with Stacie, but just wanted to add....you don't have to stop just because he is turning one. One is just the minimum that the AAP and WHO recommend and unfortunately the media kinda portrays it as "the" age.
Just know that if you both want to continue, the milk doesn't magically become less good for him the day he turns one. It still has all the same wonderful stuff in it for him and it will benefit him to continue nursing if you have it in you to continue.
I didn't intend to nurse longer, but my son didn't want to stop and being working mom I cherished those snuggly moments. I would say nursing a toddler is easier and more enjoyable than a baby because they don't take much down time like that once they start moving around. Plus you don't have to nurse them any certain number of times and usually they will understand and not mind too much if you say "not now".
Good luck!
