"Men are cool and whatever but women are f*****g warriors and capable of anything," she wrote.
Schumer continued thanking her birthing team and her husband Chris's doula, Domino Kirke — who's married to actor Penn Badgley.
"I was lucky enough to get to have a doula. Her name @domino_kirke @carriagehousebirth what do doulas do? I don't totally know But what she did was make me and Chris feel totally secure and supported throughout my pregnancy and the birth process."
"I really recommend getting one if you can. Doctor Brill and all the nurses and pediatricians at Lenox Hill and all the other hospitals I spent time in this year, thank you for everything."
During her pregnancy, the Trainwreck actress had to cancel some shows because she suffered from hyperemesis gravidarum, a condition marked by constant morning sickness that often leads to dehydration and weight loss.
"I did Pilates with strong women and went for walks. I threw up violently and felt sick mostly every day of my pregnancy."
"Hyperemesis is real and it's awful. But fuck, what they say is true. The second you give birth it's gone."
Fortunately, she found a solution.
"@hgmoms has the best research I found on the condition The only thing that helped me with my nausea was products from @thelordjones. I learned that globally 1 in 5 births take place without the assistance of a skilled birth attendant."
She also suggested how you can help expectant mothers in need of help in Guatemala and thanked her staff for their undying support after many visits to the hospital.
"@everymomcounts is a great place to donate $250 equips a midwife with a bag of medical equipment needed to provide care to hundreds of women and babies in Guatemala. All my friends. Friends I've had for 30 years or people who encouraged me to 'keep going' or telling me 'it will be worth it.' Thank you."
She felt a kinship with her encouraging female friends and medical experts who have helped her along the way.
"Every woman I encountered is so willing to help and advise you and I felt all their strength. And you were right. Thank you ladies from my family. Chris, Gene and of course Tatiana #titsleaking #wearingadiaper"
Her words are exactly what many women need to hear as they face their own challenges towards motherhood.

Schumer and her husband Chris Fischer, 39, welcomed Gene on Sunday and announced the news on Monday's Instagram post.
She humorously wrote in the caption, "10:55 pm last night. Our royal baby was born," as a nod to Meghan Markle and Prince Harry welcoming their newborn son just a few hours later.
Congratulations, Amy! You are undoubtedly a fierce warrior and a beautiful mom.
