These Little Fish Board books by Lucy Cousins are my granddaughters favourites. I introduced them to her when she was about 1 year old. They are the perfect size for wee hands. Finding the fish under the flaps of these brilliantly coloured pages never gets old. She excitedly finds and names the fish each time.
She also loves the Counting one. We use our fingers to count each fish and then trace the number on the opposite page.
