Ryan Gosling is a "very hands-on" father.

The 'Notebook' star and his long-term girlfriend Eva Mendes, 40, welcomed their first child into the world last Friday (12.09.14), and the 33-year-old actor has already started documenting their baby girl's milestones on video.

A source close to the couple, who started dating in September 2011, said: "Ryan is very hands-on. Changes diapers, rocks her to sleep - they gave her her first bath together and videotaped the whole thing."

The duo are continuing to lay low at their mansion in Hidden Hills, Los Angeles, but are getting a lot of help from their mothers, who have both been helping to keep the place clean and cook.

The insider also told E! News: "Both grandmothers are so in love and have been to the house every day."

The duo, who met on the set of their movie 'The Place Beyond The Pines' three years ago, are "blissfully in love" and their first child has brought them even closer together.

Another source previously said: "Ryan is madly in love with the baby.

"[Eva is] absolutely in heaven being a mom. She's never been happier.

"She and Ryan are just in awe of this beautiful person they created. It's a really special time for them."

The couple are yet to reveal the name of their little one nor officially confirm the birth of their daughter.
