How many pairs of shoes/sandals does a growing child need?

We bought James' first pair of shoes when he could stand up on his own and take a few steps while holding on to something/someone.

My mum would always warn us to buy a size bigger cause these lil ones grow out of it superbly fast. Well, she's right and it's so fast that after a month, a size bigger became a size too small.

So I decided to line up all of James' shoes/sandals together...

These are just some of it. He has 2-3 more pairs at my mum's place.

So..if you ask any parent, how many pairs of shoes/sandals does a growing child need? They can't give you an exact answer because the number just keeps increasing!

Cikumuffin's collection of shoes is less than her son's. Time to shop for shoes for my own? :P
