My baby is 7 weeks old, he hasn't had the best start in life and I'm putting it down to his big brother bringing home germs from nursery, he's has 2 eye infections and bronchiolitis. And now he is just constant snotty but no actual snot comes out his nose not even when he sneezes it's just all at the back of his throat it sounds like. And now I'm wondering if he has a milk allergy as he has had these types off poos for about 3 weeks now. Only once a day but if he parts some will come out too? Does this poo look normal or should I go to the dr?
