You have something to drink every time you eat and so should she. If she is too full to take a bottle after her meals cut back on the food.
Beweary of volume quotas when it comes to nutrition.
Also note that calcium is found in other foods other than dairy. Look up the nutritional content of what she is eating to see what she is actully getting. Note that she also needs Vitamin D to absorb the calcium and if she isin't getting 15 min of sunlight a day, then is she getting the Vit. D in her food? Also keep in mind that over doing the calcium consistently will cause kidney stones.
All that being said the volume of food for every child is different. I have some children in my care that take 1 1/2 oz every 2-3 hours and others that take 8 oz every 3-4 both with cereal and baby food in between. These two particular children are only two weeks apart, but both are happy, healthy and growing. Those are the most important markers.
In a four months she will be a year and you will be adding in more foods and water NOT JUICE and taking less milk. NUTRITION ALWAYS BEATS VOLUME becoming a label reader now, understanding them and knowing what healthy nutrition looks like for your child will be a much more vauable skill to have then.
Google the ingredients learn their effects and how the body reacts to or uses them. You may find she is already getting just what she needs.
