Chapter book recommendations 4 & 6 year old

[PSL1990]

Can anyone recommend me a really good chapter book suitable to read to a 4 & 6 year old? Thanks

My five year old loves the Dirty Bertie books.

We enjoyed the Mr Gum books.

My daughter (5) really loves the Isadora Moon series of books, she is half vampire and half fairy. The illustrations to text ratio is great for this age.

We have also recently purchased a series called Kitty which is a girl with cat like superhero powers from what I can gather. We haven't started it yet but looks fab.

My youngest son (6) loves the ‘trouble with Daisy’ series by Kes Grey , I quite enjoy it too my eldest son used to enjoy the ‘Stink’ series by Megan McDonald.

The Adventure Mice

The News Hounds

Original Winnie the Pooh books

For big fact books, big book of slimy things and big book of dead things are all about nature, science, ancient civilization etc done in a really fun way.

Jill Tomlinson animal books are brilliant, so well written, interesting and funny. Mine loved me reading them at around those ages, think we finished them when my eldest was 7\8
