amy,
My son is drinking 6oz now, about 5 feeds a day, a total of 30oz at least. He finished 1 tin of 900g milk powder in 6 days so which means i need to buy 4-5 tins of milk a month! About $147.50 on milk powder, expensive!
I supposed after they start taking solid, the no of feed on milk will reduce to 3x a day. Usually 2 solid feeds a day (1 lunch + 1 dinner), the other 3x of milk will be 1x in the morning , 1x around 3pm, the other 1x before bed.
