I have two children, DD 10 and DS 8 - both nearly 11 and 9 - going in to Yr 6 & 4.
Always felt that two was my lot - felt done!!!
I am 39, DH is 45, both work full time. Recently I have been considering a 3rd.....not sure why, am very surprised by this, wondering if it's related to my age, in that I'm approaching the age whereby my time is running out!!
We are financially secure, no concerns regarding this aspect, just wondering if I'm crazy......haven't broached subject with H, think he would laugh out loud initially thinking it was a big joke, no idea what he would say if I pressed on 
Anyone one else been here, what did you decide - posting here for traffic!!!
