Whilst it may send Dorothea running for cover, I’m going to talk children, specifically, potty training and sleep training. I’ll let you know when I’ve finished. 
Perhaps the two biggest early years problems you can face, we are doing potty training at the same time as sleep training. Kid A is failing to do number two’s in the right place, and Kid B doesn’t want to sleep in the right place.
Emilia, to put it bluntly, poos in her pants. Worse, she tells us this; after the event. Wee wee is not a problem, the “potty’s the place”. Sigh.
Better news on the sleep training. Here’s the secret, let them cry. Honestly, over a certain age, there is no reason not to let them cry. They will stop, and they will sleep. We got into a terrible mess because we were worried that George would wake Emilia up, so went to him, brought him downstairs and let him sleep in my arms. Bad more, because then he wouldn’t sleep at all unless he was in my arms, meaning no blogging for Paul in the evening, no playing games, no fun with the wife (you know board games, hop scotch, etc). I watched a lot of telly though, and the whole of the extended LoTR DVD.
But, enough was enough. The first night was the worst. Every half hour he’d wake and take ten minutes to stop crying and go to sleep. That last for three hours. That was three days ago. Tonight, he has woken once, and after a quick visit, went back to sleep in two minutes. Eventually, he won’t even do this. It is hard, leaving a child to cry, but it works.
