So the next adventure in parenting is introducing solid foods to the child, and there are a few recommendations before steak but it is a single source food, provided you don't season it, and maybe your child would enjoy gumming a slice?
As an explanation, there is a Bible passage about milk vs solid foods (signifying simple concepts vs more complex matters) and that is what I'm alluding to in this comic.

L: Lucy choked while nursing earlier, so she's clearly not ready for steak yet.
Y: You do... you do know there's a few steps between those, right???
