To begin making Sweet Corn & Peas Upma for babies and toddlers, we have to first get the peas and corn steamed. 

In a pressure cooker add a handful of sweet corn and peas along with 2 tablespoons of water. 

Pressure cook for 1 whistle, turn off the heat. 

Run the pressure cooker under water, open the lid and keep aside. 

In a pan, add a teaspoon of ghee. Once the ghee melts, add mustard seeds and urad dal. 

Once the mustard seeds crackle and urad dal turns brown, add the finely chopped onion. 

Saute until the onions until they are soft and translucent. 

Add in the cooked peas and corn along with salt, stir well. 

Next add 1/2 cup hot water and stir well. Use hot water instead of room temperature water in order to quicken the process of cooking. If not using hot water, allow for the water to come to a boil. 

Once you see bubbles in the water, add the roasted semolina or rava slowly. 

Stir continuously while adding to the hot water so as to prevent lumps from forming. 

Stir until the upma thickens, then close the lid and let it steam for a few minutes. 

Turn off the heat and your baby's Sweet Corn and Peas Upma is ready to be fed. 

Serve Sweet Corn And Peas Upma to you babies and toddlers along with a bowl of curd and a few pieces of chopped banana for breakfast or even dinner.
