My daughters father barely has contact with her but recently he has been asking to see her after work which i have said is fine but i have noticed that he likes to come and see her covered from head to toe in oil, would it be wrong if i asked him to nip home and have a shower, change of clothes before he comes? I am very paranoid about my daughter getting sick, i dont like confrontation and would like to avoid it if possible, what should i say?
