toddler Alaram Clock

Hi Ladies!

I know that a lot of people have jumped ship, but I'm hoping that there are enough here to answer my question. Years ago I remember some of ya'll talking about a toddler alarm clock. Do they work? Brooks (almost) 2 has been getting up around 5am, but wants to come into our room and fall asleep, we've been putting him back in his room and he'll go back to sleep. I was thinking the alarm clock might work for him. Thoughts? experiences? 

TIA
