Clothes sizes

What’s is a good amount of clothes you should stock up for newborn-6months clothes and so on?

I know for sure baby growth out of newborn clothes quick so I’m looking more into 2-4/ 3-6 months sizes. This is the only thing on my baby registration list I need help with.

My daughter was born 6lb 12oz and most of the clothes were giving out to me from people I knew in my school. Didn’t have to get her anything until she was a year old.

Im having another sweet little bean in December

Just found out It is baby boy (couldn’t be happier), this time I’m all alone I will probably will not even have a baby shower so I’m trying to buy stuff for him little by little.

Ps. If you want to share your baby registry list that will be a huge help me figure this out.
