Baby Makes Four! All the Adorable Family Photos of Jamie Lynn Spears' Newborn Daughter Ivey
PARTY OF FOUR
"I would say that being a mom is being a mom: It doesn't matter if you're in your teens or not, there should be no excuse to not be a great mother," Jamie Lynn Spears tells PEOPLE for this week's issue.
The 27-year-old singer-songwriter — who welcomed her first child with husband Jamie Watson, daughter Ivey Joan, on April 11 — is also mom to daughter Maddie Briann, 9½, whom she gave birth to at age 17.
After welcoming Ivey, Spears says, "This time, it's just been a really peaceful experience. I think the only difference is the support system I have around me."
(RE-)LEARNING THE ROPES
She adds, "I'm much more sure of myself as a young mother [now]. As a new mother with your first child, you are questioning and guessing everything."
"And as you go into it the second time, you're like, 'I got this. I figured this out one time before; I can do it again.' You have a little more confidence in yourself."
The Kentwood, Louisiana-based star says baby Ivey is "pretty on-demand" with breastfeeding — so much so that Spears once had to nurse at Maddie's softball game.
"I sat in the car at the ballpark and breastfed. I was like, 'If one of Maddie's friends sees me, she's gonna be so livid,' " recalls the former Zoey 101 actress. "You gotta do what you gotta do!"
BIG SIS TO THE RESCUE
Maddie has been a significant source of support with baby Ivey. "It's definitely a big help, having one who's a little older," Spears explains. "I can say, 'Let me grab the clothes out of the dryer.' And she can sit there with her for a second."
TEAMWORK MAKES THE DREAM WORK
"It's important to have a partner who can pick up the slack where you can't," Spears says of Watson, 36, whom she married in 2014.
"If you don't have a supportive partner, it would be a different story," she explains. "That's been the biggest adjustment: finding that balance to where both kids have exactly what they need."
HOME IS WHERE THE HEART IS
Kentwood is "where my support system is," says Spears. "It's where my mother is, where my husband is. It's where my older daughter has established her home. I think it's really important to have roots."
"I've always loved my home," she adds. "I just want my girls to grow up the same way, really appreciating where we're from, and I want them to have their familiar upbringing, which is being at Grandma's and having the same routine, the same school — I've created that here, and this is home."
