Books to keep 18 month old ds entertained

[countesscaloriecounter]

We are going on a 10 hour flight in a month and wonder if there are any books you could recommend to keep my ds entertained. He loves lift the flap books, and I'm just wondering about sticker books. Would you say he's too young for them yet? Any recommendations for activity type books that would be suitable greatly received.

Dear Zoo by Rod Campbell
You Choose! by Pippa Goodhart
Peepo! by Janet Ahlberg
It's Mine by Rod Campbell

Classics but they do the job!

Not activity as such but if he's 18 months and a boy he'll probably love Dig Dig Digging and the Amazing Machines series. We hated them-he loved them. Stickers are fine if you don't mind disembarking plastered in the things. I'd recommend those mini aquadraw things-Tesco have them at the moment. Playdoh-just a small pot or two and a few cheap matchbox type toy cars or planes and of course crayons/washable felt tips and paper.

Thanks for the repies. great suggestions
