the idea is that they support you. They won't do your housework sadly (or I would have one like a shot LOL), but othetr than that- go out with yu, swimming, chat, mother ad toddler, appointments- wahtewver you both decide would work best for the two of yu really. It's a lng term thing too, unless you don't need it any mroe (whioch knowing your story is unlikely) you'd probably have her until your youngestr eacherd 5, or until the volunteer ceased volnteering (in which case yu'd be up fr a new match)
I will point out that diferent schemes (mine was Sedgemoor) operate in slightly different ways thopugh they all have a central procedure to adhere to.
At urs you'd get a initial visit, then we'd look for a match. wen one came about (and its someone to match you, not just first on the list) we'd introduce, review a week later, then review after 2 months, then every 6 months unless we felt there was a greater need; we'd also (as managers) keep i touch by phone, and by various events such as Chriostmas parties and we ran a family group too with a playleader so we could focus on parents.
Charlotte may be able to tell you how her scheme varied from that?
