I have five, and so much of the time they would rather play with each other than have my undivided attention.
I often ask if one wants to do something with just me and 9 times out of 10 they ask if a sibling or two can do it with us. One dd does like alone time with us but the other 4 really don't seem to value it.
None of them are 'mini parents' they do argue a lot but so do many children in smaller families.
I didn't actually plan to have five of them and while I love having a big family I think I would have found it much easier to have three children. Having five is a lot of fun, but also a lot of hard work.
Lots of people say they love coming here and seeing them all playing together and the closeness we all have, and I get many compliments on how lovely they are, but people do leave quite exhausted by the noise and not many people would want to live in my chaotic home. Because it is loud and it is busy and when they aren't at school there is very little quiet in the house.
