I'm a bottlefeeder, and my 14 week old is on sma white. She goes every 6 hours & takes 8/9 oz. My friend has given me a pack of cow&gate breakfast rice.. Would you say it is too early to try her on a teaspoonful in the mornings? The sma white doesn't seem to fill her much now & I can't use the next milk up until she's 6 months.
