A bit of both like others have pointed out. Although I lean more towards a business, which I find difficult to handle at times. Only last week I got told how lucky I was to be able to look after children for money! As though I should offer to do it for free.
I care for the children in my care, becoming closer to those that are with me for 40+ hours a week as they see all parts of my family life. I feel a natural protective feeling towards them, that I don't get with children not in my care. I do want them to feel as comfortable with my home as possible, I also have private areas (mainly upstairs), but am aware that I want to be different to a nursery and am happy to think of myself more of an Aunty. But get tired with people (including my own relatives) in social occasions who think I want to look after children all the time, definitely lots of bus-men's holidays.
I also try to keep a distance, I accidently accepted a parents friend request on facebook (I rarely use it), but found myself worrying about saying things that she may not like. Like a couple of weeks ago I posted at the beginning of my holiday "YAY no kids in the house for 10 days", forgetting that she may find this a bit
, they also kept asking where we were going, I think some found it strange that I was just going to luxuriate bumming around in my own home, doing things with my own, older children. I also avoid most social occasions that parents invite me to, as it may shatter their image of me, after a few glasses of wine, I do get rather loud.
I don't miss them when they go to school, its more of a "reflective" feeling wondering where the time is going to rather than sadness, I also feel they are very ready for school and outgrowing me and my home, so its a double edge sword. One parent said to me recently, "it must break your heart when they leave", I didn't want to appear unfeeling, so sort of said, "ah well we all move on, I'm sure I will see them around".
