Girls, hi! How's it going with your saviours?) Girls, I have another question! My daughter is 6 months old, and yesterday and today she started shaking her head from side to side, like searching for a teething ring or showing "no" with her head or when babies get their teeth cut they grab toys with their hands and shake their heads back and forth as if scratching their gums...Why does she do that? Should we go see a neurologist? Just put her on the bed or hold her in your arms once and she starts shaking her head...Should we panic or is this normal? What do you think?
