Hmmm, well we agreed to start trying around when DD turns 1 - I would ideally like 1.5-2years between them as my middle bro and I were really close when we were little because of our ages being close like that so I would like it for DD - BUT on the other hand I think about how much extra work it will be with 2 so little and DH is enjoying the bit more sleep etc we have now or when she has a bad day I think but how will we cope???

(I realize I'm blabbering) I guess I'm trying to say that it's normal to have mixed feelings - and if you do fall pregnant sooner than expected - well that's why pregnancy is so long - 9 months to get well and truly used to the idea. Sounds like you've got a plan and for good reason if you're worried about how long it might take you TTC, and not being 100% isn't a bad thing - it's just means you are a normal person who is considering everything.
