help for 7 week beagle

Hi quick intro – first ever time getting a dog i’m 22 living in a family of 4 with my mum not working -thought it was a good time since she’s not working to get a dog

So now onto the dog——— ..7.5weeks old male beagle that is really energetic during the day, it has a few naps scattered about but for the most part it’s really hyper. how can we get it to nap more? ..We have round teething to be a problem it keeps biting my socks and i can feel its teeth any help with that? ..few accidents here and there but for the most part my mums been pretty good at training it outside. Anything we can be doing better? ..Night times are okay had 3 nights with it first one was a struggle but last two have been okay we put it in the crate for 8:30 it wakes around 11ish to go toilet which i take outside and the around 1am where it’s normally me going into the kitchen letting him know i’m there then he dozes off to bed till around 5 where my mum will wake him up and take him out. Don’t mind this routine so hopefully this lasts. anything i should be doing differently at night?

But more importantly hoping it doesn’t drain my mum out as she’s already showed a few signs of cracking and it’s only been 3 days, what should be done to make life a bit easier?
