My son gets really stimulated with tub play so we introduced the book and it kind of is a slower paced activity while he bathes. It’s great for water activity out of the bath too. The water wow (by Melissa and Doug) brushes work perfect for it.
Even though I knew this book was “magic” when I ordered it, I was nonetheless amazed the first time we got it wet! It really is so cool and my kids love it. My 4 year old will stand on a stool at the kitchen sink playing with it even when it’s not bath time!
