It's also not appropriate for a premature baby until it's at least 3 months old (adjusted).
To make sterile formula (which an early baby like this needs) you need to pour boiling water INTO THE FORMULA powder and then let it cool. Boiling the water and letting it cool and then adding it to the powder does nothing because most water in the West is perfectly safe to drink.
So the baby brezza (while fine for most kids over 3 months old, not withstanding the issues it had/has with adding the right amount of powder) is not appropriate.
Also, taking care of a newborn is easy (sorry if I'm bursting any bubbles here) they physically can't stay awake for long periods of time, they sleep, eat, and shit - that's it. They also can't move anywhere. By the time you've fed them (after they've slept and shit) it's time to put them back to bed.
By the time a baby is no longer a complete potato you have to entertain it. Then it starts to get mobile and the real "fun" begins."
