I’m only 7 weeks so I know it’s super early but when do y’all think is the right time to start getting the nursery ready and buying stuff for baby?

This is my 3rd pregnancy and I have 1 living child. I lost my first at exactly 20 weeks due to IC. I had complications with my second and was hospitalized 3 times for preterm labor. I was able to carry him till 30 weeks. We didn’t get anything until after he was born because we feared the unknown. I’m wanting to be better prepared this time around.
