Loving reminder that giving up hugs isn't easy.
Parents will catch how complicated Felix's feelings really are and can use the book as a way to discuss their own kids' sometimes contrary emotions. For example, Felix may want to punish his mother just the tiniest little bit for taking away his baseball, but he doesn't want to punish himself. So when he feels jealous seeing his baby sibling getting lots of cuddling, he decides that maybe he can move the "no hugs" date back a day because clearly "Mama was missing his hugs." Parents can point out in the picture that Felix's expression and body language show that maybe it's not just Mommy who's doing the missing.
