Hi Okhud, here are some settings which may help you - both can be adjusted from the Settings window (tap the cog wheel button)
1. Turn "Autoforward Mode to "Always ON" so all slides will play automatically
2. Turn "Tap to Next Slide" OFF - if you currently have this turned on, that will likely cause slides to go forward when your baby taps the screen
Note that you can still swipe to move forward or backward even though the slides are on autoforward. If you like, you can change "Next Slide Swipe" to "2 fingers" so it will be a bit "harder" for your baby to advance slides himself.
You can also cover the top right corner of the screen during the lesson so he won't tap the Exit button accidentally
