As she adjusts to her life as a new mom, Jessa (Duggar) Seewald has her family to support her.

The Jill and Jessa: Counting On star relies especially on her big sister Jill (Duggar) Dillard and mom Michelle Duggar for advice on parenting baby Spurgeon Elliot, her 4-month-old son with husband Ben Seewald.

When it comes to Michelle, 49, who has raised 19 kids of her own, Jessa says the 19 Kids and Counting matriarch “has a lot of wisdom.”

“She has raised just about every personality type, so I really enjoy learning from her,” Jessa, 23, tells PEOPLE in this week’s issue.

“But my baby is really still young, so most of my questions these days are about breastfeeding and when to change diaper sizes,” she adds.

As for her sister, the communication might not be face-to-face as Jill, 24, continues her missionary work with her family in Central America, but it’s just as valuable.

“I have the opportunity to video-chat with her,” says Jessa of Jill, who has an 11-month old son, Israel David, with her husband Derick Dillard, 26. “[We] catch up and talk about how Israel is progressing and [I’ll] ask her a question about having a little baby. She is a really great resource for me.”

Jessa and Ben, 20, welcomed Spurgeon (nicknamed Quincy) on Nov. 5 after an intense, 48-hour delivery.

“I can’t believe he’s really ours,” Jessa told PEOPLE exclusively at the time. “It is so amazing. He’s a miracle.”

In the months since, the proud parents have shared several adorable updates of their smiley son, including a sweet slideshow of his first Christmas.

Their experience as proud, happy new parents will continued to be documented when Jill and Jessa: Counting On returns March 15 at 9 p.m. ET on TLC.
