Normal Feeding?

Hi mamas, before I ask my question I would just like to say that i know every baby is different, and he has put back on weight he's lost, and I know he's going through a growth spurt already. Just would like some reassurance that I'm not messing up or if I should still be waking him to eat. I don't have a set pediatrician so I also haven't called the one we have for now, bc I'm not very trusting of them.

My newborn, is a week and 4 days. He had 4 oz before he went to sleep at 7pm tonight. This was his first 4 oz bottle. He currently slept until roughly around 1am. He got changed, and ate 3 oz and fell back asleep. Should I wake him at the 4 hour mark to eat or just let him wake up on his own for the next feeding/changing? I think 4 oz is alot for him but he drank the entire bottle and was happy and fell asleep.. I'm a paranoid/anxious mama 😭
