Hello, When you are starting your baby on solids and introducing them to each new thing how do you do it? By this I mean... Do you feed rice cereal and a new thing and if so do you feed all the rice cereal and then the new thing, or alternate them spoon for spoon? When you've established something is fine do you move it to another meal? When you've established several things are safe do you alternate everything so that baby remembers them? Or do you start mixing veges up for following meals? How do YOU do it? Cheers.
