I have 3 dc (8, 6 and 4). I would love another child and my 3 dc are always saying they'd love a baby (esp the girls who are baby mad) but tbh the thing holding me back is how fair it would be on them.
It is only now that I feel my head is above the water and am getting slightly more organised. Previous to this I have felt like we were swimming underwater. Sleepless nights, breast feeding, mess, three kids all running off in different directions, car seats, carrying one, one in the buggy, need I go on!! Now it is quite calm, they can amuse themsleves for periods of time (also half kill each other at times!) but we can get things done.
I feel it could only be easier than before. At one stage I had a 4 year old, a 21 month old and a new born. Surely with 3 older dc a baby would seem a breeze 
It is only because I feel they would be held back by another baby that I am unsure. Oh and feeling like I would be pushing my luck. 3 normal, lovely deliveries, 3 healthy babies (although one miscarriage which was hard) would I be tempting fate?
Anyone else felt like this?
