The OM Chant and my daughter

[Cnblasiann]

Hi everyone. I just want to say first that I am inexperienced with meditation, yogi or really many things spiritual. I have always been curious, starting research here and there but getting discouraged because I don't want to open doors I can't close. But, I've recently given birth to a sweet baby girl. She's 10 months now. A few months ago, I saw this cute video with a guy using the OM Chant to calm his baby, and did it myself on a whim, to my daughter to see what she would do. She was fine, happy and smiling, but when I did the chant she got REALLY upset... She was 5 months then. I did it again after a little while out of curiosity, and then realized it really is the chant that makes her upset. 5 months later I thought about it and did it again with the same reaction. It's almost fear. I know better now and don't want to upset her so I'm done with it. But what could this mean?
