Awww! Welcome to YT
For pups that age, I´d advise you to leave his food out 24/7 so he always has access to it, at least until he is about 3 months old
At that age, I´d also give mine a swipe of honey (you can get Nutrical so use that) on the roof on their mouth twice a day just to make sure their sugar levels didnt go down

He´ll be fine, it´s much like having a baby

Make sure he eats every few hours, even if you have to hand him to food yourself...oh, and don´t expect much of anything in the potty training department yet either lol.They pee ALOT at that age, and they don´t have control over their bladder yet either, so by the time he realises he needs to pee, he´s already half way through doing it lol

I´d start with the potty training at around 10+ weeks, because if you decide to crate train
now, he
WILL pee in that crate because he will not be able to hold himself, and no pup wants to pee where he sleeps you know?
Not much else exept CONGRATS and ENJOY!!

He´s adorable!!
