Like all good parents we have a monitor system to keep an ear on his room. Nothing special just a mic in his room and a speaker in our room, the usual. But our speaker has a series of colored led's that as the sound gets louder, more light up. Our rooms are very close together and the mic is sensitive enough to broadcast sounds from our room. We were playing and our little Einstein rolled over and looked straight at the speaker on the nightstand and proceeded to yell. Louder and louder. Over and over again. He wasn't upset, not crying, just making the speaker light up. Simply incredible that this little dude already has that thing all figured out.
Ok. Done bragging. Just amazed at these little fellers.
Hope everyone is well!
