Many thanks for all your advice. I daren't say it but he seems to be settling in and it's becoming less, oh god I've said it now
In fact he is sat on my neck as we speak styling my hair for me! His new thing now is biting my hand when I try to pick him up, so we have had a few times out! He still takes a wideberth away from the husband but he has been taking food from him, so I think it will be a long process! Thanks again and I will post again with an update.
