At the dinner table my granddaughter dropped meat, daughter picked it up and put it back on 4and halfyr old's plate.I was shocked and I guess it showed tho I didn't say anything. Daughter said they often eat things that they dropped, even outside! She proudly said that she ate gum she found on the pavement when she played out as a child 'and it did her no harm'. They have a garden that is 'used' by her cat and the three who live next door. I did not argue or give any opinion,g'daughter was at the table and a bit emotionally upset as she is in her first term at school. I have been thinking about this all night and wounder if I should tackle her in private, at all or just send her the definition of hygiene and toxocariasis. Why am I so worried when clearly daughter doesn't care.
