I like to antagonized the baby.
That seems mean. Why do you antagonize the baby?
I do it on purpose and I joke around with him. He loves to be jump scared and he loves it if I scare him.
Even if the baby likes it, people will think you are a child hater if you antagonize a child on purpose. It would be good to play with the baby in a different way.
But it's great to see the baby happy.
It is and babies can be happy with joyful things too. And it won't make others think you are evil from antagonizing the baby.
