I'm 33 and have an 11 yr old with autism, I was very poorly whilst pregnant with hyperemesis and then had a child who thought sleep was for the weak, an unsupporive partner, and PND so I never even considered a second and always felt a bit sad about it but have had a lovely 11 yrs of one to one with my son. 
11 years on I now have a slighter sleepier child (yay) and a lovely partner and we have both said we might like a child together (he has no kids) after we've lived together for a bit.
I'm aware that as I'm 34 in September and we are planning to move in together soon (we've delayed living together purely because of logistics until now) that my biological clock is ticking. Should I be concerned? What do I need to bare in mind?
I'm also aware that due to some surgery I've had that I will need a Csection, so that will be all new to me too and won't be able to drive for a bit afterwards.
Anyone conceived with a big age gap between kids? How did you find it all?
