Are boys weedier than girls, health-wise, or is it just mine? While both my DCs are 'healthy', DS (5 months) has already been on antibiotics twice, hospitalised once for infection and currently into the third week of diarrhoea/coughing virus. DD, although smaller and much grouchier in temprement, had none of this, and I don't think it is just being the second child and being exposed to more diseases... My Mum is convinced that boys are more susceptible because girls are 'the template', genetically. Can there be any truth in this...?!
