personally i would NEVER have a large family, a big age gap between kids ect, i had the worst time ever, and now kinda dispise kids, had to bring up my brother from the age of 10 coz mother 'couldn't be bothered' when parents split again i had to be the responsible adult, blended family came into it, now have 3 younger step siblings, there great (fake smile) the house is noisey you can't get your own space, fight for attention, i'd have to wait to spend any time with dad untill all kids in bed and settled (bout 9pm) then hr infront of tv until i was 18, then we'd disapear 1s a month to pub.
pros- didn't get a shock leaving home having to fend for myself, i'd had plenty of experience
you know how to be a parent already
budgeting comes naturally as you've watched you family do it - e.g. i'm like the only student with a good amount of savings
many pros for parents i suppose- can take a bit of a back seat let your older ones do it
cons - loud
attention fighting
loose childhood
live off a shoe string (school trips out of question for most families)
can never get away (for me it was uni, death or find a job get into to debt having a house)
no alone time
i'm sure some people are cut out for large family lives... me erm no i'm now struggling to live in halls with other people :P
