Her weight is just below the 10th percentile and height just above the 50th percentile for her age. Her weight is not off the chart which is good. For an 18 month old you need to switch to Pediasure as the milk source and not baby formula. An older child needs more then baby formula. Use Pediasure in place of milk and the formula which will give her extra calories and protein.
As a guideline for an 18 month old child should eat the following:
Dairy 4 feedings a day – Milk-use Pediasure (4oz), cheese (½ oz), yogurt (½ cup), or cottage cheese (¼ cup).
Starch 4 feedings a day – Cereal (¼ cup), pasta (¼ cup), rice (¼ cup), bread (½ slice), or crackers (2).
Fruits & Vegetables 4 feedings a day – Fruits (including 100% juice limited to only 4-6ozs) & Vegetables (¼ cup).
Protein source 2 feedings a day – Meat or fish (1oz), egg (1), or beans (¼ cup).
She should eat 3 meals and have snacks between meals using the foods above to be spread out throughout the day. Hoped this helped you.
Thanks a lot for your response.
