Ryan Gosling loves singing to his baby daughter.
The 'Gangster Squad' actor is "infatuated" with four-month-old Esmeralda - who he has with girlfriend Eva Mendes - and is keen to encourage her to be interested in music while she is young.
A source said: "Ryan sings to the baby. He loves it. Sometimes he'll make up his own songs and include her name in them. It's very sweet."
Last weekend, the couple were seen on one of their first date nights since their little girl was born and insiders say they have finally been able to get out as the baby - who Eva is breastfeeding - is developing more of a routine.
The source explained to E! Online: "The baby, who hadn't been sleeping well, is on more of a schedule.
"That's why Eva and Ryan were able to go out the other night. They knew they had a few hours in between feedings
"They loved getting out of the house for a bit and enjoying some alone time."
The 40-year-old actress recently joked she has had "some of the wildest nights ever" since giving birth because she and Ryan, 34, were trying to care for Esmeralda without the help of a nanny.
She said: "I'm doing it without a nanny for now but I'm open to the idea of having a nanny in the future.
"Esmeralda has two amazing grandmothers and incredible aunties who come over and really help me. But as far as a nanny or a night nurse, for me that part of being a mother at this early stage is the struggle of not being able to sleep and not knowing what I'm doing and really going through it with her and battling out those nights."
