is what my 8-month-old likes to shout out of nowhere, really, really loudly, then he giggles. I thought it was funny but today when he did it in a cafe where I was meeting a friend and her baby, he made her dd cry by doing it suddenly... and the whole place seemed to turn and look and then she told me I should be discouraging it. Surely this is just a passing phase of him trying out new sounds? Am I supposed to be doing something about it? If so, what?!
