Nuri
So this is my first time being pregnant and I have no clue how many pieces of clothes I need for the baby for each month stage? 
How many clothes for: 
Newborn: 
3 months: 
6 months: 
9 months: 
12 months: 
Also I live in NYC and when the baby will be born it will be fall and for first 7 months he will be wearing basically winter clothes.
