My boyfriend has been smelling a foul odor from our baby girl Ember that is nauseating him. she is 5 weeks old. I don't smell anything, I think she smells good. we are trying to figure out what the smell could be. do squirrels have a particular odor? does squirrel feces have a strong smell? could it be the esbliac formula that smells? we just wanna know what the smell is, so my boyfriend doesn't get nauseous anymore from it.
