We've been having a lovely time with
Elephant Wellyphant. It's hilarious and perfect to share with mixed age children. The link above is for the publisher's website but I don't think there is a link to buy so here is
another one!
There are a few bits inside the book that mean you can't really leave your toddler alone with it - spinning wheel and pull out tabs etc but the whole premise is beautifully suited to 18 months plus although I'm sure you could use it with younger children too.
It's a very simple play on the word elephant. There's Smelliphant (pull a tab and out pops a 'parp' - greatly loved by my four year old!). A poorly, spotty Unwelliphant. A Cinderellaphant (turn the flap and there she is ready for the ball). And of course as the title suggests an elephant wearing wellies - a Wellyphant.
Nick Sharratt's fantastic artwork is perfect for this format and style of book and his sense of humour and the ridiculous can be seen to great effect here. Love it!
