My son is three and we still use it every night.
I have no plans of retiring it. I dont think ill get rid of it until he is old enough to masturbate, I dont wanna hear that.
I like having it because I can hear if he isn't sleeping, if he is playing, or idk lets get off my sanity for a second and say if a baby thief broke in through his window, id be able to hear him say, "MOMMY!". I like to be able to hear everything that goes on in his room.
Sometimes he wakes up and just says, "Mom, thirsty." or "Mom, Potty." in a very regular voice. We taught him not to leave his room at night...so im able to respond to him at night through the monitor.
I have heard mom's say they got rid of the monitor the moment their child became a toddler at 12 months. I really don't know when most mom's ditch the monitor and im curious about it.
So tell me your monitor stories & opinions please : )
