Stocking up on diapers! HELP

Okay I’m a first time mom so bare with me 😬

I want to stock up on diapers before my little one comes in July. There’s no doubt in my mind that this baby is gonna be the size of a line backer lol im 5’6, plus size and his dad is 6’2. So we’re pretty tall. So that being considered what sizes do you think i should stock up on and how much of each size should i get? I am on a budget because I’m no longer working and a single mom so I’d rather not over stock and waist money😣

I also have eczema and psoriasis. My skin is beyond sensitive so I’m counting on my son to have sensitive skin too as i did when i was a baby as well. So I have to consider that too

This is my current inventory on diapers

Size newborn of pampers pure count 76

Size 1 of pampers baby dry count 120

Size 1 of huggies count 32

Size 2 of pampers baby dry count 37

I know it’s not a lot at all hence why i wanted to stock up today and spend around $200. What do y’all recommend?

Thank you 💕💕
