Hello mam. Your child weight is absolutely fine for 1 year as per WHO charts. Weight loss is significant as per your weight records. Thats unlikely to lose that much in 2 weeks unless baby is really sick with fever/breathing issues/diarrhea. Doubt with weighing scale/technique. Please measure with same scale with bare minimal clothes everytime.
1 year old has tendency to start refusing foods
Please spend more time with patience and good positive playful interaction with your child to give 3 meals, 2 snacks in addition to breast milk and 1 litres of water a day.
Next Steps
increase amount of food/duration of feeding.
weigh your baby consistently same machine with bare minimal cloth.
consult in person if your baby is not passing urine atleast 6 times a day/irritable/not sleeping properly/lethargic.
