I have a DD who is 2 (today!) and I am 29 weeks pregnant with my second.
Being pregnant the first time was a non-event, no sickness, not too much tiredness, etc, etc.
This time: felt ill for weeks, terribly tired but also a raging insomniac - wake anytime from 2am and lie there for hours. Cry at the drop of a hat (or a teaspoon or biscuit on the floor), slightly down rather than excited, feel uncomfortable all the time and so annoyed with work.
I know each pregnancy is different and I know having a toddler isn't helping but come on! I think it is a girl (though don't actually know) so not sure I can blame hormones!
