Diaper size

How often do you change diaper size?

My baby is upgrading a size every month.

He is 6 months and 7 kg (as of 5 and half months) and in size 4.

He is not a chubby baby he is normal in size.

Its really hard to know how many i need. I buy in big amounts each size coz its more affordable and so far have used all. Except a few size 3 left at my parents’ house.
