Unhappy Babies on Product Packaging

I always find it mysterious when I see packaging for a baby product with a picture of an unhappy baby. Was it that hard to get the kid to smile?

Kelly has a great baby carrier called the Lillebaby. It offers six different carrying positions, and according to the promotional materials, the baby looks miserable in all but one of them.

Then there's this infant bath seat. It's a fine product, but the child looks constipated here.

Maybe I have a skewed perspective because Alice is an insanely happy baby.

Honestly, most of the time she looks ecstatic just to be alive. It's almost creepy.

This is how you get Alice to smile. Step 1: Make eye contact. Step 2: There is no Step 2.

I wouldn't want her shilling for baby products. But I guarantee this is how she'd handle it: "I may not understand what you're selling, mister, but I'M GOING TO ROCK THIS THING."
