Sibling bonding! Jessa Duggar is currently pregnant and expecting baby No. 3 with her husband, Ben Seewald, but her oldest son looks like he might be the most excited for the newest addition to their family. The Counting On star took to Instagram to share a very sweet moment between her 3-year-old son, Spurgeon, and his unborn little brother and or sister.

“Totally looked like baby was responding to big bro’s sweet kiss (and little bro’s monster truck driving)! 💙👦🏻👦🏼,” the 26-year-old captioned the clip. “Watching Spurgeon anticipate the arrival of his new sibling has got to be one of the sweetest parts of this pregnancy. 😍 Henry will pat my belly sometimes and say ‘Baby!’ because he sees us do that, but I don’t think he truly comprehends what’s about to take place. ☺️ Little less than a month to go! #BabySeewald3.”

The reality star has not been as active in sharing regular baby bump updates on social media as she has been in the past. Where she would normally share monthly updates about the progress of her little one’s growth in her womb, she’s only shared two baby bump pics so far of Baby No. 3, and it seems like she’s refraining from posting too much about her third pregnancy out of respect for her sister-in-law, Lauren Duggar (née Swanson). Lauren got pregnant with her first child with Josiah Duggar at the same time that Jessa got pregnant with baby No. 3, but Lauren, unfortunately, suffered a heartbreaking miscarriage.

#25weeks Pregnancy— such a precious gift, and definitely not something I take for granted. As we look forward to meeting our baby, we’re also feeling an exceptional amount of grief over my brother Josiah and sister-in-law Lauren’s loss of their baby. Lauren and I shared the exact same due date. We have cried so many tears, both together and apart. My heart aches for them. I weep when I think of how difficult it must be for her to see me pregnant in the very stages where she would’ve been— right up through the baby’s due date. And yet, even in a flood of emotions, there are perplexities of the human heart that may cause us to want to clam up or remain silent through such a trial. Because of this, many people feel like they’re walking this road alone. It is true that speaking for the sake of filling silence is not needful and is often hurtful. I’ve watched Lauren converse with people who have been unknowingly insensitive, and I am amazed by her graciousness. I’ve heard some try to give reasons or explanations, not realizing that their unsolicited opinions might be very painful, like salt to a wound. One might never know the tears you cry at night as a result of their words flowing back through your head. Often times, “I love you and I’m praying for you” along with a hug are quite sufficient. We do not need to fill every silence with words. But at the same time, conversations of lost dreams should never feel suppressed. Silence can stifle healing, but a carefully chosen word may work to help bring life and healing to the soul. We must all reinforce the fact that emotions over a life lost are not something to be resisted. They’re not wrong, and you should never think that for a moment. If you’ve lost a child, know this— YOU ARE A MAMA, and you will never cease to think about and cherish the life you carried… **swipe left to read more**

Back in February, Jessa shared her first baby bump photo and she shared a heartfelt message to Lauren. “As we look forward to meeting our baby, we’re also feeling an exceptional amount of grief over my brother Josiah and sister-in-law Lauren’s loss of their baby,” Jessa wrote. “Lauren and I shared the exact same due date.
