I cycled when my son was 10 months old. Got a BFN, but several months later got pregnant with a frozen embryo from that cycle.
I would not recommend rushing things much - you want to give your body sufficient time to switch gears from pregnanfy/BF to conception - but October to summer sounds reasonable to me, as long as you stop BFing at least two months before you cycle.
