Second book in the series from Isla Fisher, my son unexpectedly really enjoyed the first so we read this too. A third is coming and looks like we'll be searching for it.
Three separate adventures, all based on the rainbow-haired babysitter looking after Jemima and Jake, and this time, baby Zara joins the fun and havoc.
The children play pirates, go swimming and attend a wedding, each time Marge making their days fun, bringing (and preventing in equal measure) chaos, with Jemima telling us all about it.
I read this aloud, and find Marge a little hard to 'voice', she's a tiny person but with an upper class background. I also wanted more of her in it in the last story, at the wedding - it finishes without returning to the babysitter.
Mildly amusing, my son seems to enjoy them, they are a different sort of chapter book, with an adult lead character who is essentially another child.
