Hi. My dd2 is 6 weeks , weighs 9 pounds 6 ounces and is formula fed - Aptamil First. She is already having 6 ounce bottles, 5 times in a 24 hour period which according to the tine is more than she should be having, although I appreciate the info on there is a guideline only. She drains them every time and cries out hungry afterwards. I don't want to increase the volume, and am therefore wondering about using Aptamil Extra which I understand is for hungry babies.
Has anyone had experience of using this?
