I'm not defending them here, but to be fair, they can't look at the floor like they're about to have a breakdown 24/7, the media are hounding them every minute of the day they are bound to catch them smiling at some point or another, they have two other kids to think about and while those smiles will be fake they are no doubt for the benefit of the twins.
Bear in mind also that they risk having the twins taken away so i imagine they are trying not to bring the two babies into the feelings of sorrow, kids pick up on that.
