I don't think anything can really ever prepare anyone for being a parent... People will tell you until their blue in the face that it's hard. And I don't think until you are in the midst of it - you don't actually realise how hard it is. The sleep deprivation, the constant cycling of feeding, changing etc... It's bloody hard! I think also being a man and trying to come to terms with all this psychologically is very hard.
There's probably tomes I could write on this and one day I may... as a friend suggested I should title it How to Raise Children with Style, Grace and a Sense of Humour. Looking back at it now - I think having a sense of humour when raising children is probably the most important thing.
Larry and I never really fought. The girls were born and home and all of a sudden we were fighting almost every day. Part of it was probably the lack of sleep, the stress of dealing with twin infants, the stress of dealing with Larry trying to find a job, feeling isolated in the country. The people who promised us they'd help never really came through (I'll touch on this later too).
At this point in time it's very easy to look back and say we were very lucky. Which we were. The girls weren't sick - they had no major health complications (which for premature babies is a very good thing!). They both gained weight at the correct rate (Olivia a bit slower but she was getting there gradually... funny thing is she still won't really eat!).
So we fought and fought and fought - generally over really stupid small inconsequential things, like tracking how much the girls were eating at each feed. Why dinner was always so late (we were eating at about 9pm), the lack of sex, the amount of time Larry was spending in the garden. I will also admit I was stressed about the impending visit of my mother (which I pulled the pin on as I couldn't cope with the idea, and I honestly think if my mother and I would have been under the same roof - it would have been a complete disaster [gay men and their mothers!]). Pretty much the usual things that parents fight over.
But at the time it did just feel very hard. And I guess on the plus side we got through it!
