Sorry you had a rough day Rosie - if it helps my three fight less now there are 3 of them - think its more to do with whoever is in a bad mood can now have the space to just be (as opposed to having a bored brother bugging them) whilst the other two play.
Mine all look different to - ds1 like his daddy, ds2 just like me, ds3 not quite sure yet, he's sitting on the fence at the moment sometimes like me sometimes like dh. I always said he'd be the one to make to make the other two look like brothers as they are complete opposites. You had a good chance he may look like you x
