What kind of baby clothes?

Ma
Hi everyone! FTM here and super excited to meet my little man in September, but I'm having trouble deciding what kind and how much baby clothes for each size I should stock up on. So far I've purchased a couple (maybe 3 or 4) of zipper footies with mitten cuffs for 0-3 months. I've also purchased a few onesies for 0-3 months. How many newborn clothes do I need, and what kind? Footies? Onesies? Sleep sacks?   What about 0-3 months? 3-6 months? Any recommendations would be greatly appreciated! Thanks!
