I'm so worried about my 3 and 2 years old nieces. They even get diarrhoea every now and then and at times the 3 years old one says her tummy hurts. I remember when she was a baby she used to suddenly start crying, I guess she used to get belly ache. Their mother have no sense of food and kitchen hygiene. She would use poultry, meat or fish and spread the mess all over the kitchen's work top contaminating with everything. When she's done cooking, she never clean up properly. Half of the residue remains and you literally can smell the fishy odour left on the surface. Then she goes and put their milk bottle or plates, cups and utensils there and wouldn't even wash throughly before using them. DN's bottles stinks. The dishes has stains or grease on it sometimes. She'll be serving them food that's been contaminated. Would not pay attention to see if there's any molds on fruits and quickly gives them one or to rinse whether they get clean or not she doesn't see. They drink from a bottle that water been in it all day and some of the food particles went in it. She leaves foods uncovered for hours, and half cut onion peeled or unpeeled on the worktop for days. I am worried about my brother too as he also eat from her, he doesn't seem to realise how dirty she is. I feel if I point these issues out she will take it negatively and I don't think she'd even change. She just don't have sense for it. Am I being over concern?
