getting pregnant straight after birth?

Pip
My son is 7 months and I'd love to have another one. It's tiring and hard work but I'd like to get this stage out of the way. 
Is there anyone who has a very close age gap between babies? Please tell me what it's like and if you'd of had it any other way? 
My son is also disabled, he has a bowel condition, so we spend some time in hospital and he's fed via his nose, but I don't want this to stop us having a bigger family and we cope just fine with his disability, I've never known parent hood any different so this is normal to me.
