I worked as a nanny before having Ashlea, and started looking after three kids after I had Ashlea and I would take her with me. She was almost 2.
Four kids under 4 was fun!!
I loved being able to take ashlea to work with me, and it mean she had little friends to play with all day instead of being stuck with me all the time!
I would love to find another part time nanny job where i could take Ashlea with me again, but not alot of people are that open to bringing your own child along.
The share nanny idea is a good one.
Just make sure you check their references, that they have a first aide certificate and ask for a police check too.
