First of all, the answer is yes, you do get the full Baby Shark song with one press of your little one's finger with this book. Depending on if that is press #1 or #201 likely depends on how much you will love that feature.
With that said, my 15 month old LOVES this book. She quickly got the hang of pushing the buttons to hear the songs and it entertains her for minutes on end (which is a long time in Toddler time). Seriously, she'll sit with this book for a good 20-30 minutes listening to all the songs.
Besides baby Shark, there are 9 other Shark themed hits that you will recognize Like "There was a yellow shark and shark was his name OH, S-H-A-R-K" (sang to the tune of There was a farmer who had a dog) and twinkle twinkle little shark. There is even a holiday remix of Baby Shark.
Your kid will love this book. You will hate this book until you realize you got 20 minutes of peace, then you'll just sing along to Where is Daddy Shark and accept it.
