How much on money speny on baby is too much

Hi, recently we had a baby girl 👶 and are ovet the moon and enjoying our early parenthood.

I have noticed that we have been a lot of money on things (toys, dresses, accessories etc..) ~1lakh till now.. 20k for clothes, other accessories ~70k (crib, car seat, stroller, dining chair, baby carrier, breast pumps etc etc..) during these initial days..

All products in baby category are super expensive (talk about muslin clothes) and kids quickly outgrow them, making them irrelevant (our daughter is just 20days old and whatever the rompers we got for newborn is already to tight for her).

How do you convince your wife that something is too expensive and not worth to buy? Whenever I have given hints on this, she mentions that you spend money on this and that and we shouldn't "kanjoos" when it comes to baby👶.. My wife is not ready to buy second hand items or use items from relatives (at least things like accessories not clothes).

I can easily afford all this (>1cr CTC), but when do I start things about spending excessively?
