Hey Jackie! Welcome! 
Congrats on the new addition!
I think the important thing with Chis is to not baby them(too much,lol). A dog is a dog. Treat him like a big dog, do not reward him when he is afraid with cuddles and kisses, but do reward with a lot of praise when he is near hubby, even if it's by accident. Also, your husband has to make it worth while for Manny, so put hubby in charge of giving Manny his daily treats, Manny will quickly learn that being around his papa is good. It's normal for a pup to be a little skittish at first, stay patient and do your best to expose him to different people, places, sounds, etc. Up to 4 months is the BEST age in my opinion to train your pup, they suck it all up like a sponge. Maybe your hubby can get down on the floor and with help of delicious treats and praise try to teach Manny fetch. It'll take time but will be a great way for the two to bond.
