How many of NB, size 1, and size 2 diapers do you need?

I have a 7 year old so it’s been a long time since I bought diapers. I have one big box of NB and a smaller box of NB and a huge box of 1s. I’m wondering if I should get one more smaller box of NBs. My daughter was 7lbs 14oz when she was born if that helps
