A little confusing, you state about cooking baby foods but then call them toddlers. If it is 4 and 6 years and toddlers is correct I wouldn't think you would be doing any baby foods for them. I have a 3 and 6 year old and they eat adult food pretty much. Just normal breakfast fare for them.
I prep veggies for snacks and quick cooking for my kids. 3 and 4 years old. They like an omelette or egg scramble with their choice of veggies in the morning, then snack on those same veggies and hummus throughout the day. Fresh fruit and granola with yogurt is another.
