Just out of curiosity, when did your infant / toddler start being able to 'slide to unlock'? I have a 14 month old daughter who loves to go for my phone, mainly because I rarely let her have it. Currently she is still enamored with the single button (thanks Steve) and is content with activating Siri and occasionally pulling up the camera or starting a song. However, I do feel that the day is near when she will unlock her potential to unlock my phone, and I feel nervous about this. I try hard not to let her see me unlock it. So parents, what has been your experience?
