I like:
That I'm around for my children and can take my son to school etc
That I have a lively house with lots of sparkly characters and feel like I have a lovely extended family
That my children have all these friends of various ages
That I have met some lovely families who I also socialise with outside of work at times and have all become friends
That my youngest (aged 2.4 and knows nothing but me childminding) gets sooooo excited when all his 'friends' come back after I've closed for a week/after the weekend and that he jumps for joy when mindees stay overnight, even though he's kicked out of his room for it.
Being my own boss and doing things the way I want to do them
Bringing in an income/being successful
Having so many tinies to look after and watching them grow into proper little people (had them start from 5 wks old)
Being out and about (groups, park, country parks, splashing in muddy puddles, chucking leaves at each other, feeding ducks and all the picnics etc :))
I Don't like:
That although I'm around, my own children are pushed away whilst I'm sorting all the other children out
That although I can take my son to school, the school run is so manic that I can't spend time with him helping him with some of his work like lots of the other parents do (I know most schools don't) - obviously I'd not be able to do ANYTHING though if I was employed.
That my eldest sometimes just wants to be able to play on the Wii or chill with some tv etc. but can't as it's not appropriate for the other children
That when my children are a bit off colour but I'm still able to work, that I can't give them the extra time they need as still busy with all the others
The Paperwork (HATE it!!!!!)
Parents who are regularly late and come up with all sorts of excuses
Parents who bring a sick child in knowing full well the 'rules' and then they have to go home anyway but has now passed it on to everyone else (causing me to loose money if I catch a D&V bug!!!
)
Having to chase payment (rare but annoying on occasion)
Being ill and just wanting to rest but instead having 5/6 children for breakfast from 7am and having to plod through the school and nursery runs with them all and having 4 aged 3 and under to entertain when I just want to lie on the sofa!
Children's behaviour at times
Wearing rubbish clothes all the time 
The extra washing
Dinnertime (I HATE preparing dinner and trying to entertain 6 children at the same time!)
My house looking like a nursery
The impact it all has on the family (although obviously I've mentioned the pros to this)
