Since I don't know baby language, I tried to communicate in such a way with a friend's daughter who is about one and a half years old (now almost two years old).
At first, we were good but last week, they arrived with her still sleeping.
My friend said that it was almost time for her to wake up, and I accidentally sent a small yellow colored energy ball to make her wake up...and she quickly got angry waking up.
That was a bit of my mistake, but her parents comforted her after that and she was okay.
I can create energy ball not only from my hands, but also from my forehead (third eye), so I don't need to point my hand or it'll be too obvious to other people.
