DD is seven weeks and has just started smiling but she seems to be reserving the majority of her smiles for DP and my Mum which I am trying to be brave about but am finding a little upsetting. I've tried lots of smiling at her, peek-a-boo, big exaggerated kisses, silly songs and gobbling her toes - any other suggestions? I know it sounds silly but I'm feeling a little hurt that DP and my Mum only have to look at her and she beams but I don't seem to be inspiring many smiles no matter what I try...
