My first child was quite punctual - I went into labour on my due date.
I am currently 33 weeks pregnant and like most heavily pregnant women I am fed up and wanting it to be over. Because I was fortunate with dd's 'punctuality', I have convinced myself that the next baby will likewise be either on time or perhaps a day or two early.
Am I living in a fools paradise? Is there any evidence to suggest that if you are 'on time' with one, you can expect the same with your 2nd. If I am deluding myself I need to know now - otherwise I will be bitterly disappointed when 19 April comes and goes!
