DD is still all over the place. Sometimes she can eat about 6 or 7 or as little as 2 or 3.There's really no rhyme or reason to how much she eats when.
A good rule is 2 to 2.5 for every pound they weigh. So, if your LO weighs 10lbs you should shoot for 20oz to 25oz in a day. Also, if they are averaging for the week somewhere in the 'right' range, thats ok as well. Some days LOs eat more than others, just like some days we're more hungry than others.
