Concerns About My 9-Month-Old Daughter's Weight and Growth - Pediatrics

My sister is too thin?


Hello, Doctor: My little daughter is currently 9 months and 18 days old.
She weighed 2600 grams and was 49 cm long at birth.
Today, during her vaccination, her height and weight were measured as follows: height: 65 cm, weight: 6.7 kg.
She consumes about 700 to 750 cc of milk a day, and her intake of solid foods depends on her mood; sometimes she eats a lot, and other times she doesn't eat at all (she has fruit puree, juice, porridge, and biscuits).
Her sleep pattern is normal; she wakes up at 7:30 AM and goes to bed at 8 PM.
She is very active and can already pull herself up and move along the side of her crib, but she cannot stand without support yet! I feel that she is too small and have asked the doctor, who also mentioned that she is underweight but did not advise me on whether I should take her for further examination.
I am very worried and do not know where to find information.
Could you please reply to me as soon as possible? Should I take her for further examination? Can I go to a regular pediatric clinic, or do I need to go to a large hospital? Which department should I visit? Thank you very much, Doctor! I am really anxious!

Hello: A nine-month-old baby girl has a height of 65 cm and a weight of 6.7 kg, which is around the 3rd percentile according to the growth chart.
Currently, her development is normal, but she is considered short and underweight.
If the parents are of a smaller build, it is likely that the child will also be smaller due to genetic predisposition.
Based on the description, the child's appetite is not very good, so it is recommended to establish healthy eating habits (such as creating a positive eating environment and providing timely encouragement), and possibly supplementing with multivitamins to promote better weight gain (assuming there are no underlying issues such as chronic diarrhea, malabsorption, or other diseases).
At this stage, egg yolk and other similar foods should be introduced.
In terms of height, aside from genetic factors, it is also important to check for any endocrine issues.
I recommend taking your daughter to a pediatric metabolism and endocrinology department at a medical center or regional hospital for follow-up examinations.
Thank you for your call.

Dear Concerned Parent,
Thank you for reaching out with your concerns regarding your 9-month-old daughter's weight and growth. It's understandable to feel anxious about your child's development, especially when it comes to weight and nutrition. Based on the information you've provided, let's break down your concerns and provide some guidance.

Firstly, your daughter was born at a weight of 2600 grams (approximately 5.73 pounds) and a height of 49 cm (about 19.29 inches). At 9 months and 18 days, her current weight is 6.7 kg (approximately 14.77 pounds) and her height is 65 cm (about 25.59 inches). According to growth charts, your daughter's weight and height are below the 3rd percentile, which indicates that she is smaller than most children her age. This can be concerning, especially if you feel she is not gaining weight adequately.

It's important to note that growth patterns can vary significantly among infants. Factors such as genetics, nutrition, and overall health play a crucial role in a child's growth trajectory. Given that your daughter is active, has a normal sleep pattern, and is reaching developmental milestones (like pulling herself up), these are positive signs. However, her weight does raise some flags.

Regarding your question about whether to seek further evaluation, it would be prudent to consult a pediatrician, especially since you mentioned that your previous doctor noted she is "too thin." A pediatrician can assess her growth more comprehensively and may refer you to a pediatric endocrinologist if there are concerns about hormonal or metabolic issues affecting her growth.

When you visit the pediatrician, they will likely conduct a thorough examination, including:
1. Growth Assessment: They will plot her weight and height on a growth chart to see how she compares to other children her age.

2. Dietary Evaluation: Since you mentioned her milk intake is around 700-750 cc per day and her solid food intake varies, the doctor may provide dietary recommendations to ensure she is receiving adequate nutrition. It's essential for her to have a balanced diet that includes a variety of fruits, vegetables, grains, and proteins.

3. Developmental Milestones: They will assess her developmental milestones to ensure she is progressing appropriately.

4. Medical History: A review of her medical history, including any illnesses or feeding difficulties, will help the doctor understand her growth pattern better.

In terms of dietary recommendations, at this age, it's crucial to introduce a variety of foods to encourage healthy eating habits. While breast milk or formula should still be a significant part of her diet, you can gradually introduce more solid foods, including pureed meats, grains, and vegetables. Avoid adding salt or sugar to her food, as her kidneys are still developing, and these can be harmful.

If your daughter is showing signs of picky eating or inconsistent appetite, try to create a positive mealtime environment. Offer her a variety of foods and allow her to explore different textures and flavors. Sometimes, it takes several exposures to a new food before a child will accept it.

In summary, while your daughter's growth may be a concern, there are many factors to consider. Consulting with a pediatrician will provide you with the guidance and reassurance you need. They can help you determine if further testing is necessary and provide you with strategies to support your daughter's growth and nutritional needs.

Remember, every child is unique, and growth patterns can vary widely. With the right support and monitoring, you can help ensure your daughter develops healthily.

Best wishes for you and your daughter’s health and happiness!
Sincerely,
