We're in that exact situation right now. We're going to start TTC #2 in Oct too

I have mixed feelings but I know I want at least one more child and I'm not getting any younger. We had originally planned for 18months between pg so that's coming up in Nov. I BF DS until he was 11months old and while I was BF there was no way I could even consider having another. Once I stopped BF it was like a switch got turned on and all of a sudden I could face being pg again. I also wanted to get my body back to how it was pre-pg before I did it all again. I've well and truly done that now (I weigh about 3kg less than I did before conceiving DS and I'm super fit ATM ) so that's a good thing but at the same time I'm thinking I bounced back so well after DS do I really want to stuff myself up again and risk not springing back into shape again? Its selfish to think this way but I can't help it.

Anyway, I know I haven't offered any advice but you're certainly not alone in having cold feet about #2.

Good luck
