Babies love the 'Where's?' series by Ingela P. Arrhenius and 'Where's Mr.Dog' is our personal favourite as it features familiar objects; many that are a child's first words (dog, cat, ball, bird, cat, tree etc).
Five beautifully illustrated spreads show a series of friendly pets hiding behind bright felt flaps. And there's a mirror on the final page!
These books are particularly great for babies from four months old as this is when object permanence sets in. Object permanence involves a baby's understanding that when things disappear, they aren't gone forever.
