My dear baby was crawling around some days ago and then tried to grad some charging cables and our cell phones that were hanging down the shelf.
I saw her from a distance and was chewing food.
So all I made was a "hm!" sound. Like "hey!". She turned around and looked at me. I shook my head and made a "no no" sound.
She wasn't to happy about it but she did indeed take her hand away.
That was the first time we communicated over a distance. I was happy that she simply did what I asked her! Let's hope I can keep it that way.
