Hats, Thomas just loves them. They don't have to fit, they don't have to be his but he will gladly wear just about any hat.
When I say he will wear just about any hat. I am not speaking just of the cute little ball cap type hats. It is rear we wear this type of hat. Oh no, this is not the preferred type of hat.

Instead, he really loves sock hats.
This one actually belongs to him.

It makes lots of sense to wear a sock hat
outside in the winter time to keep warm.

It doesn't make as much sense to wear them indoors
even though we do often because we love sock hats.

Did I mention, they don't have to fit
and they don't have to belong to him.
He loves his brothers hats!
That is OK because big brother hated this hat
because of the bill on it.

Personally, I think it is cute!
It can be 20 degrees outside or it can be 70 degrees outside.
I can't usually get out of the house without Thomas putting on some type of hat.
Most kids have a favorite stuffed toy or blanket, not Thomas it is all about the hats.
Have your kids been obsessed over something?
