Forewarnig of “every kid is different”, so ymmv.
One of my kids would fall asleep while nursing as well but keep sucking in his sleep! But hey you found what works for you (see forewarnig).
For the first 2 weeks (at least) yeah that’s all they do: eat, sleep, fill diapers. However it’s never too early to have some cuddle/play time. Gentle caresses all over, like a light massage, especially after bath time with some oil maybe. Singing (or even just talking to them) is great as you’ll soon start to see them reacting to your voice.
As you’ll surely know their eyesight is not great at the beginning, but you will notice when they get more alert of their surrounding.
Skin to skin contact also is a great way to make them happy.
Apart for that, it’s way too soon to start worrying about “let’s not make a dick of this human”.
I recommend a book called “wonder weeks”, and once you have recovered from sleep deprivation, “raising boys”. BUT EVERY KID IS DIFFERENT, so don’t take them as the absolute truth, more like guidelines and food for thought.
Maybe get him some sensory toys, it’s a great way for them to start learning to explore stuff.
And finally, remember that kids learn by copying what they see. A lot of kids grow messed up because unfortunately they come from messed up situations.
He WILL make you mad and angry. Remember that anger is a secondary emotion, you need to be able to breathe and recognize what you’re angry at. And you can tell them, and also that you need a minute to calm down. If they see you dealing with strong emotions in a healthy way they’ll learn too (but also they WILL make you made on purpose as they learn boundaries by pushing them. Yes, they are little sociopaths).
There’s ton more stuff of course but the fact that you care and you’re concerned is already a good step. We all mess up in some way, but being able to put your ego aside and say sorry to them is a big thing. Don’t feel like you should always know the answers, we all make it up as we go!
Congratulations and good luck!
Also because death by shaken baby syndrome is unfortunately a very common thing
