Saving for No.4

As I was chatting with Amy just now, I just realised that I have not plan on how much to save for the arrival of No.4.

Well...actually not that I do not want to save up but I just don't have fix income to plan my saving. Our current income is just enough for our current monthly expenses.

So I am just trusting God to provide for No.4's arrival. Praying that money will fall down from the sky!
