Volume for the sounds is a bit too low - we try to find a volume control but unsuccessful. The next week we came to the store, we tried the other moos and they are the same. The Bluey sound book are louder.

Sound volume to low can't here it

The sound isn't loud enough for my one year old granddaughter to hear. We replaced the (expensive) batteries. There was no change in the volume. There isn't a way to increase the volume either. She loved the book, but gets upset because of the sound (or lack of).

The volume is so low you can hardly hear it and the buttons are very hard to press
