I can’t decide if this is a real post, and perhaps English isn’t your first language, or if it’s AI. The way you refer to the mother of your child and your newborn son is so stilted and cold, it’s almost red flags.
but, to address your issue:
”The baby at this stage does not see or comprehend emotional attachments or bonds the same way as we do (these seem to me advanced concepts which need to be learned over time and not given innately, if given innately why we have serial killers...). They don't understand routines either. The priority for guardians is to feed the baby, change and keep him in a safe place. Values to help him make better decisions in future can be taught at later stages.”
Sorry, no, you are very very wrong. Babies do know who is caring for them, and do need continuity and connection. These are formative weeks and you and your partner need to be as hands on as possible. Attachment is incredibly important, your baby needs to be held, nurtured and interacted with. Not just fed and clothed and ‘kept safe’
“The baby will settle into outside world with time and become more manageable especially at night as their stomach gets larger and they can hold their waste longer in their body. They do not need night nurses or nannies after a while.”
Babies and small children wake at night for the first few years, not weeks. This is why mothers get 12 months met leave, because caring for a baby is intensive and can be exhausting.
My suggestions for supporting your partner:
look into a doula, housekeeper or cleaner. If you want extra help make it domestic support, someone who will look after your partner so she can care for the baby and heal from the birth and trauma. Maybe a lactation consultant to help her breastfeed, bottles and formula seem like the easy option but are actually a lot of work, and she may well find it emotionally healing to breastfeed after a traumatic birth.
you don’t need a night nanny or a million gadgets, you just need to give your partner plenty of support, emotional and practical.
