Clothes!

I’m a ftm due in June. I’ve already went crazy shopping for clothes for my little man but I wanted some advice on how many size newborn onesies/pants (size newborn clothes in general) that i should have for him? Also I live in Texas and he’s due in the summer so he won’t need layers! (I know babies can be born too big for this size and go immediately to 0-3 but I’m pretty certain he will not be since me and his fathers families have yet to have a baby over 7 pounds) please comment your advice!
