A useful means of networking with female television executives. Note that baby photos can be used as a form of networking currency, with a value roughly akin to that of a well-painted Warhammer figurine to an Aardman animator (quite a lot). HOWEVER: do not use pictures of babies you have found on the internet 'because they look less mental'. Or if your baby is particularly odd-looking, at least take care that selected photos roughly approximate your own child's skin colour/racial origin. Do not attempt to substitute photographs of particularly cute kittens, puppies, baby crocodiles etc - WOMEN ARE TRAINED TO NOTICE THESE THINGS.
When you have a baby, people positively expect you to have odd-smelling stains all over whatever you happen to wearing. If you are a full-time writer, the chances are you would have had odd-smelling stains all over whatever you were wearing anyway, but it's nice to have an excuse.
RAPID CALORIE LOSS DUE TO BREAST FEEDING:
Note that this only applies to the female babykeeper. Constant snacking to keep strength up 'for the baby' on the part of the male babykeeper/writer will only lead to writerly flesh taking on a flabby, dough-like texture. Referring to this as 'winter bulk' will not convince anyone.
Observations as to the wisdom of Mother Nature in making babies all cute rather than 'being covered in scales and having multifaceted eyes like a wasp, because if they looked like that you'd be less likely to look after them' will not be greeted as a breakthrough in evolutionary theory akin to that of Charles Darwin's 'Hey, what if populations evolved over the course of generations through a process of, oh I don't know, let's call it natural selection'.
Writers may find their dialogue skills drying up a little at this early stage, as most of the day's conversation consists of singing 'Hey now little baby, why don't you stop screaming' to the tune of the 'Ooooh Bodyform' advert from about nineteen ninety two.
'I'LL GO AND GET THE WARM WATER':
A useful phrase to bring out right as soon as you've spotted a nappy change is imminent, as this gives you a useful job to do, whilst simultaneously manoeuvering the female babykeeper into the position of prime nappy-remover by the time you return from the bathroom.
'I"LL TAKE THIS AWAY THEN'
A phrase to be used at the end of the nappy changing process. Take the dirty nappy in a careful, yet firm manner, to suggest that this part of the deal is AT LEAST as onerous as the actual nappy removal and maintainance bit.
Remember: the phrase 'ooh what a shiny bum!' IS ONLY TO BE USED INDOORS.
