Little Mouse
Here you will find illustrations I have used in a project of mine, a picture book for children. 

A little mouse, tired of the usual mother's milk, decides to leave the den while his brothers and sisters are taking a nap.
Looking for new things to taste in the bushes, he will meet other baby animals.
At the end of the day , tired, famished and a bit scared, he will decide that it is safer and much easier to enjoy the "old" milk.
