Well done on bfing your son for as long as you both want to!

My DD is nearly four and has bf every day up until Friday last week. I'm not sure if she has weaned completely, or it's just circumstantial (we were up early and away for the weekend), but the only bf she was still having was one in the early morning, between 5:30-6:30am, where she would come in and feed and snuggle, going back to sleep.

I'm fairly sure at my DD's age her bfs have mostly been for comfort, rather than hunger, but I like the extra sleep in the morning too! Also, she's getting great protection from the colds that she's exposed to at pre-school and playing with other kids, so I think that value is fabulous!
