The following pictures will help illustrate how to feed your child in such a way as to require a garden hose to clean up after him:

Step 1: Be sure to feed your child bright orange carrots on a night when he's especially tired. He will then proceed to soothe himself by sucking his thumb, regardless of the presence of said carrots.....

Step 2: Be sure to turn your back for a moment, so you have no way to prevent your child from rubbing his very tired eyes with the same fingers he just had in his carrot-filled mouth...

Step 3: Be sure to repeat steps 1 and 2 over and over again until your child is thoroughly coated in pureed carrots. Then, after the carrots have been completely ground into your child's face, rendering his skin a delightfully glowing orange slightly reminiscent of an Oompa Loompa, give up all hope of cleanliness and allow your child to fulfill his weeks-long dream of grabbing his spoon and feeding himself pureed peas.

Step 4: Laugh as hard as you can and prepare the garden hose, as you will need it to remove peas from the back of your child's head and carrots from his eyebrows.
