Hilaria Baldwin posted a photo of herself breastfeeding son Rafael on Thursday, Aug. 6

Relaxing with Rafael! Hilaria Baldwin shared more than her usual yoga poses via Instagram on Thursday, Aug. 6. Instead, Alec Baldwin's wife shared a sweet photo of herself breastfeeding the couple's newborn son.

"Rafa's favorite spot. There is no one right way to feed our babies, but this week marks #nationalbreastfeedingweek and I would like to extend my support to mothers who have taken this path," the yoga instructor, 31, captioned the pic.

She added: "In the end, regardless of our methods, #AllMommiesUnite and whatever way we love and nurture our children is beautiful, perfect and inspiring."

The proud mom announced on June 17 that she and the 30 Rock alum, 57, had welcomed their second child. The couple, who shared exclusive photos of Rafael with Us Weekly last month, are already parents to daughter Carmen, 23 months. (Alec is also dad to 19-year-old daughter Ireland, whom he had with ex-wife Kim Basinger.)

"She wants to kiss him, hold him, sing to him, and feed him food he can’t eat. She’s a good big sister," Hilaria told Us at the time.

"It’s his first son," she added of Alec. "He can’t even believe it. Alec does other things, [he doesn't] change diapers."
