I have three and the youngest is about to go to school. Having the third nearly broke us - financially, emotionally, physically, matrimonially - and I can't believe we have got this far in one piece and soon all three will be in primary school. I am early 40s and even having the last one towards the end of my thirties was so much harder than the first at the beginning of my thirties, so I am not really being serious, and yet... that niggling feeling persists. Presumably this feeling will persist however many I have when the youngest stopped being a baby. But did anyone actually do it? And was it a terrible mistake? Talk some sense into me please!
