Greetings weight of 7.8 kg for a one-year-old girl is within the normal and healthy range on standard growth charts. Every child grows at their own pace, so tracking her personal growth trajectory over time is most important. It is a myth that babies naturally experience a fever or illness with every developmental milestone. Milestones like rolling, sitting, crawling, and standing do not cause medical issues or elevated temperatures. Teething may occasionally cause mild irritability or a slight, low-grade temperature, but never a true fever.

Consult with Pediatrician physically for further evaluation and treatment

Birth weight 3.2 kg, current weight 7.8 kg at 12 months. Expected weight at 1 year is approximately 3x birth weight = ∼9.5-9.6 kg. As per WHO growth chart for girls, 12 months weight: - 50th percentile: ∼9.5 kg - 3rd percentile: ∼7.9 kg So *7.8 kg is at the lower side of normal (around 3rd percentile).* It is not alarming by itself if the child is active, achieving milestones, and following her own growth curve consistently. *What to check:* 1.  Weight trend, not single reading - Plot on growth chart 2.  Length, head circumference 3.  Feeding history, appetite, complementary feeding after 6 months 4.  Any recurrent illness, anemia If growth velocity is maintained and development is normal, observe with diet optimization. *2nd Question - Fever with milestones:* It is a *myth*. Developmental milestones like rolling, sitting, crawling, standing *do NOT cause fever*. What happens is: - During milestones, babies put hands/toys in mouth more, leading to more viral infections - Teething does NOT cause high fever. It may cause mild irritability, drooling, gum itching, mild temperature (<100.4°F). If fever >100.4°F, look for other cause like infection. Advise: If fever occurs at any milestone, it should be evaluated as an independent illness, not attributed to milestone. Recommend: Continue balanced complementary feeding, regular growth monitoring, and consult nearby Pediatrician for a detailed growth chart plotting.

Weight is normal.
