Mine does that when she is mad, heh, its part of her temper tantrums, and she has done it since she was itty bitty.
Is he doing it out of no where? Or is he crying or upset when he does it?
If it is totally random and for no apparent reason, i would totally take him to the doctor and ask about it.
If he is doing it when upset/crying then I would say its normal, Kaylee does it still sometimes when she is pretty mad.
