She has a blocked nose, coughing, constipation and has become a really fussy eater.She is also violently sick 4-7 days out of a month.aside from this she is a healthy happy wee girl.has anyone one else has the same issues? Is it possible it could be an allergy the dairy ? Just need help doc are jyst useless..
