Hi. My ds (6mths old) has recently started shaking his head from side to side (i.e. as if saying 'no' very fast) - has anyone ever experienced this behaviour?
None of the books say anything about this being a normal developmental movement for a baby, so I'm wondering whether or not he has an ear infection or a visual problem?
Advice would be great as I'm a wee bit concerned that I am not taking it seriously enough??
Thanks
