First of all, Hi and welcome to YT. You will learn a whole lot on this site. I have in the year and 1/2 I've been here. You might want to go to the other forums and just peek at the posts to see how other mommies and daddies deal with some of the issues you are having.
As for your baby crying, he's a little guy and he's been taken from what he has known. His little world has been changed and he just probably wants some reassurance from his new mommy. Make sure to give him lots of hugs and reassurance. He should settle down after awhile. If you are set to crate him, you need to be strong, he will cry to get out. I would not crate him for long periods of time though. And if he is a puppy, you will need to take him out at least every 2 hours (I would do it every hour with him being 11 weeks old) for potty break as well as just a break.
As for following you around, that is just what they do! They love to be with their owners. They are very socialable. Enjoy it. You and hubby will need to learn the "yorkie shuffle". lol. That's a whole new way of walking-schuffling so you don't take a chance on kicking or stepping on him. I kicked Hot Rod a couple of times that he would stand back from me.
They are fast little boogers! They are called the "zoomies". lol. That is how Hot Rod got his name!
You will get mixed reviews on which food to feed on here. Hot Rod was on Royal Canine when he came home to us. I truly believe that he had an allergy to it because he had very dry itchy skin. A lot of people will tell you that Eukanuba is not a good food choice either. I personally feed Natural Balance Rolls. I have been through lots of others such as Innova, Merrick's, Calfornia Natuaral, Evo, Wellness-just to name a few. I would choose one of the better foods for your baby. This you can get a lot of info on in the Health and Diet forum. I am also sure that someone with much more knowledge on this will come on also.
As for crying at night, is it possible that you can put his crate in your bedroom? As I said, if you are set on crating, do not let him sleep in your bed, you will never be able to go backwards--lol! They have a way of getting what they want and will wrap you around their little paws quicker than anything!
As for hubby getting "fed up", dogs can sense things. I would try to make sure that hubby bonds with him as well. It is important that animals feel loved and accepted otherwise they will be nervous animals-in my opinion. By the way, what is your baby's name? Would love to see pictures of him. I bet he is adorable! I hope some of this helps.
