Cutest thing your SO has done so far :-)

JK
My husband went on a business trip and brought home a good night book and pjs from my hometown, Philadelphia. It's the cutest book ever all about Philly :-) living in Germany so get homesick a lot. 
What was the cutest about it is how my husband explained how he can't wait to read to our baby and use picture books to tell stories in German. We will be a bilingual family. 
I also found all this reading material and books in his suitcase... Thought I was the only one doing the research, been leaving tabs and pages marked for him to read but apparently he has been doing lots of reading too :-) of course we talk about it but was a surprise to see the reading material he bought as well.
