Eva Longoria is going 'big' for son Santiago's first birthday

Eva Longoria cuddles up with her now one-year-old baby boy (not to mention her firstborn!).

Santi has brought pure joy and bliss to Eva's life. The Grand Hotel actress loves to share candid snapshots of life with her baby on her social media channels. 

And daddy, Pepe Baston, is just as enamoured with his little bundle of joy, seen here chomping down on a toy as Pepe kisses him. 

Eva shared this adorable picture of Santiago showing four tiny little teeth on Mother's Day, captioning it with, "My first Mother’s Day! I don’t even remember life before this little piece of love entered it! Everyday is a blessing I cherish with all my heart! Thank you for choosing me stinky butt! I love you papa!"

"Vacation Mode!" Eva wrote here. She can't get enough of her sweet boy!

This photo was posted to commemorate Santi's fourth tooth with the baby boy showing off a bright smile to acknowledge his quick growth from baby to soon-to-be-toddler!

Namaste, says little Santi! Is he already partaking in some serious yoga moves, a possible yogi in the making? The sky's (erm, ground?) the limit for Eva and Pepe's little lovebug.
