are you keeping him inside a cardboard box?. i would recommend you to get a playpen rather than keeping him in that box. the space seems limited.
His still a puppy, when letting him run around . close supervision is needed. as his still a puppy, he tend to be playful and curious and will nibble on anything they see and may even swallow it.
Its normal for them to wine but there several ways you could calm them down, leave a ticking clock beside it, a warm bottle at the place he slp, on the radio . many ways.
Check our pet forum or the internet to know more.
hope this information helps.
Good luck and, nice puppy you have
