Here are some ridiculously cute photos of babies in NICU units dressed up for Halloween

There's nothing cuter than a Wonder Baby! Except maybe a baby dressed as a mouse...or a caterpillar...or a mermaid.

(CNN) — Sure, you think you’ve whipped up the cutest, most enviable costume for your kid for Halloween, but you haven’t seen anything yet. These babies are here to show you up.

Neonatal intensive care units across the nation are dressing their charges up in wildly adorable costumes. Some of the units, called NICU for short, give parents the opportunity to dress their babies for a friendly costume competition. Others have crafty staff on hand to create imaginative outfits for their patients.

Either way, the babies are an adorable sight to behold.

Here are just a few for you to obsess over. Thank us later.

How precious! Some fresh baby peas snuggled up in their pod at Advocate Children’s Hospital.

Each year, nurse Tara Frankhauser at Children’s spends months crocheting special costumes for each baby, taking their individual personalities into account.

This sweet little mermaid seems a little upset that someone pulled her out of the sea.

So young, but so strong! Wonder Baby is saving us all with her undeniable cuteness and ultra-strength sleep powers. This little warrior is definitely going places this Halloween.
