Hello

Thanks for choosing this platform

20 month old baby should be offered home food.There should be 3 major meals with 2-3 snacks in between.
Each major meal should be a serving of 2 katori. Babies of this age are more interested in playing rather than in eating.
Baby should be served a variety of food item to avoid the boredom.
You may give rice,roti mixed in thick dal with added ghee.Cooked vegetables should be added to the meal to meet the demand of minerals and vitamins. Khichri XXXXXXX sooji ka halwa,kheer,ragi,idli may also be given.
Filled paratha with added butter is a good breakfast.Give a glass of milk twice a day.Fruits like papaya,banana,cheeku XXXXXXX mashed apple should also be given as snacks.You may add pediasure to the milk to increase the nutritional value.
Avoid giving junk food,colas.
Avoid sharing from the same pot.Serve him from different pot and ensure that the child finishes the serving.
Teach your child to wash his hands with soap and water each time before the serving.Sit by the side of child and help him in finishing the serving.

I hope this helps.
Please let me know if you have any more query.
Wishing for your baby's better health.
Regards
