sheepgirl...I would think, with most cm's now, that it has become far more difficult to even become a cm, etc...it really is because they actually enjoy working and being with children and for whatever reason they prefer to work from home, i.e. most often this wold be family commitments...
however, I am sure there are those that well, for whatever reason chosen it, but well, possibly not with the right ideas....I went to see a cm, for my es at one time...and well, they were a bit like what could be described as, well, trailertrash...the house was not juist messy but very dirty, and it weas honestly to god, like a scene out of Harry enfields wayne and Waynetta scetches....I am not making this up...I think their hearts were in the right place, and I am sure they meant no harm...but, now I am not all that fussy about childcare, but, well...I would not have felt comfortable leaving my child there...don't get me wrong they had plenty of times...but it wasn't a really good childfriendly encironemtn, I mean, whielst I came around to look around, they actually had some kind of daytime TV on etc...so, I really don't think they did all that many activities...etc...ykwim...
I was actually a cm at one point, but I truely hated it....looking after my own Baby was one thing, but the Toddlers and preschoolers of others I found a real challenge...it just wasn't for me, and I gave up as soon as I realised that, because I felt it was unfair on all parties....
