I'm a real beginner.. only doing it 4 months and we don't have any other children in the house, so we can 100% dedicate our lives & time to it...
It has made a huge impact on our lives, and it did take some getting used to...
I love it. Its frustrating, its very emotional, its frightening, I live in limbo - the 'unknown-ness' of it all I find very hard to deal with - I'm the type of person who likes to know what is happening, timescales etc, and with fostering (or at least in my short time of fostering) you don't get much security, and seem to be the last to know anything.
Saying that, our LA I find brilliant - no complains whatsoever - I get great support, the money is good (altho I think we worked it out at something like 3p an hour) and I don't think we'll ever have to wait long for a placement (as we are not picky).
I can't advise you on what is best for you and your family. Be under no illusions that it will change your life (it HAS to be for the better) and that if you think you've not got much time now.. gosh, with all the running around to contact, meetings etc etc you will have to do!! Just make sure you've got a great support network around you.
Good luck,
