Hilaria Baldwin is getting real about what a body really looks like right after giving birth.

“I took this yesterday when Leonardo was about 24 hours old,” the yoga teacher and wife of Alec Baldwin, 32, wrote Wednesday next to a mirror selfie showing her belly a day after giving birth to her new son. “I did the same thing right after Rafael was born.”

She continues candidly, “It always makes me a bit nervous to do something like this, but I feel that in the age of such strong body shaming, I want to do all that I can to normalize a real body and promote healthy self esteem.”

“Many of you know that I love to show the process of life’s experiences on the body and I am a firm believer in how a good diet and the right balance of exercise make us happy, healthy, and strong,” Baldwin, who was wearing only an underwear set by Heidi Klum Intimates, added in the caption. “So from here on, I want to dedicate the majority of my #366daysoflivingclearly #hilarialcm daily posts to getting back in shape and I invite you to do it with me.”

The new mom of three also shared more details surrounding her newborn’s birth.

“Did I have a c section?: No, I pushed him out,” Baldwin writes. “Where are all the pads for bleeding?: I took them out briefly to snap this pic as there is a limit to how much you need to see.

“Where am I?: in the hospital room bathroom #glamour,” she adds jokingly. “Oh, and no filter. Just brightened it up a bit.”

Baldwin is a big proponent of keeping a positive outlook about body image not only for her Instagram followers, but for her children.

“I’m very careful not to put myself down in front of [daughter Carmen Gabriela, 3], like, ‘Oh my God, I don’t feel good today,’ or the typical, ‘Oh I feel so fat’ or, ‘Oh look at me, I look terrible’ kind of stuff,” she told PEOPLE in May. “I’ve learned that that can be very damaging to children.

“I try to be very positive to the people around me. Like, ‘Oh wow, doesn’t she look beautiful?’ Or ‘He’s so sweet,’ or, ‘That was such a nice thing that he did,’ ” she added.
