Speaking of blocking the home button, one of the most frequent requests we've seen from parents is for a way to keep toddlers from pressing the Home button—either accidentally or on purpose. You can avoid accidental phone calls, and the frustration resulting from your baby accidentally exiting his or her favorite app, with Paperclip Robot's BubCaps. Each BubCap is a small piece of plastic that adheres to the front of your iOS device and covers the Home button. Rather than rendering the button unusable, BubCaps increase the amount of pressure required to press the button, so it will still be accessible by adults, but not by most children. The company says BubCaps are also easy for an adult to remove, but not a child. BubCaps are available in three different strengths: Regular (for toddlers using an iPhone and iPod touch), Ultra (for toddlers on an iPad and older kids on an iPhone and iPod touch), and Max (for older and stronger kids using an iPad). A four-pack of a single strength costs $5; the company also offers sampler packs for $5 and $7.
