thanks upahill.
i am a lone parent meself, with no family, and when dts came along, and ds1 was seven, i had only one friend with a child the same age as him.
having twins forced me to make new friends with kids around their age. i didn't roll up to a toddler group trying to palm the kids off on total strangers!
to be fair boffin, i trust my judgement, and get to know somebody on their own merit before i'd ever leave my child with them.
for eg when you meet a prospective parent, they usually pop up in more than one place.
maybe i'm lucky, but i live in newcastle, in a place called heaton, and most people know or have heard of other people, or whatever - six degrees of seperation and all that. either through primary or high school, toddler or play groups or the pub!
my point is that the dearest people can be found out there - but not unless you look. also, why is there anything wrong with being open about that from the off? most other people have things they can't do without help. no (wo)man is an island.
