Theo Rex turned one month old on April Fool’s Day.

London insider tip: If you’re going to waltz around the city with a newborn baby, you sure better be ready to have long, in-depth conversations with British grannies about how lovely the baby is. Woe is me, I get to brag about my charming, adorable kid to a rapt audience. It’s a real trial, it is.

Theo’s overall aesthetic is grumpy old man who occasionally disarms with a beaming, gummy grin.
