Hey Sarah. I do a bit of babysitting (when I can get it lol) so,

1. Is is usually in their house or is it possible they drop thechild at my house?

I go to the parent's homes. It's easier for the child and parents.

2. Is it usually paid into a bank account or is it mainly cash in hand?

You can get it paid into your account, I'm happy with either but most people will just give cash in hand.

3. Do you think the clients would tend to mind if i have my 4 year old with me while looking after theirs?

Hmm, I think this just comes down to personal preference. I think if the child you're minding is a baby it would be more acceptable, but if the child was the same age, well it could go really well or it could be a disaster. I'd be inclined to say it would be a problem for me if my child was 3+.

4. Would having my own child be an advantage as it shows I know what im doing?

Maybe..? A lot of people have children and parent terribly though haha I think the fact you have a cert in child services show you know what you're doing

5. Is housework usually added into the service?

Again, unless specified, it's personal preference. I usually wash any dishes that are in the sink, load/empty the dishwasher, things like that. Only if I get the chance though, like if the child/ren are asleep for example. I charge $15 an hour, purely because it is an easy amount to give in cash (never any loose change involved) and I feel $20 is just too much.
