Chapter books for a 5/6 year old boy?

[idlenook]

DS is 5.5 and loves reading, but is growing out of his old favourites (Julia Donaldson, Oi Cat etc). He has a bedtime story from me every night and then reads independently until he falls asleep. This week, I've read him Peter Pan and Esio Trot, and he read Fantastic Mister Fox on his own last night (he's quite into Roald Dahl at the moment and has asked me to read him Charlie and the Chocolate Factory next).

I'm looking for books to read to him but particularly books he can read independently, and would love to hear your recommendations!

You can get Winnie the Witch as Chapter books, rather than picture books.

Paddington bear?

Has he read the Julia Donaldson chapter books (The Snake Who Came To Stay, Mr Birdnest and the House Next Door)?

We have read endless Beast Quest, Dinosaur Cove and Magic Tree House (not 13 story treehouse at this age).

Try the Bear and Rabbit books.

Dinosaur Cove
Toto the Ninja Cat
Famous Five
Amelia Fang
Julius Zebra
Mr Gum (although my 6 year old isn't as keen on these but I'm sure ds1 liked them at that age)
Jeremy Strong books (My brother's famous bottom was a big hit)
Jonny Duddle's Jolley Rogers series

Jeremy Strong
Captain Underpants
Faraway Tree
Professor Branestawm
Proper Thomas the Tank Engine
Dick King-Smith

Thanks everyone - off to look at these on Amazon I'd forgotten about Dick King-Smith, used to love him!

The Bad Guys

Ones I read to ds at that age:

Little House Series (especially loved Farmer Boy)
Enid Blyton's Adventure Series
Lone Pine Series (still his favourite)
Swish of the Curtain series
Cue for treason

Olga Da Polga by Michael Bond

Horrid Henry is a firm favourite here (DS2 is 7 but ASC so much like a younger child iyswim)

Famous Five & Secret Seven
