Gone fishing!

On Thursday, Erin Napier, 35, snapped an adorable photo of her 3-year-old daughter Helen learning how to fish with help from her grandfather.

In the sweet picture posted to Instagram, Helen's granddad holds her hand as the two overlook the lake together while she's dressed in a red checked dress.

"Fishergirl and pappaw (w tangled pool hair) 🎣," Erin captioned the cute shot.

Earlier this month, Erin shared a heartfelt Instagram post in honor of her husband Ben Napier, whom she said has been offering her plenty of support in the weeks since the birth of their second daughter, Mae, on May 28.

"If he's not scooping me up off the sofa as I'm still recovering from surgery, he's mixing a bottle or taking Helen swimming," Erin wrote, alongside a photo of Ben feeding little Mae a bottle.

"And I have kissed him every time he's in arm's reach because I know exactly how lucky we all are. 😍," Erin continued. "A reminder for those with spouses: tell them often - 'thank you for everything you do for us.' and MEAN IT."

Ben took his wife's advice, saying in the comments, "Thank you for EVERYTHING you do for us, lover."

Back in May, Ben and Erin told PEOPLE they were looking forward to seeing Helen, whom the couple welcomed 10 years after their wedding, as a big sister.

"While we are excited to have another daughter to love, we are more excited to see the bond she and Helen will have," the pair said. "They're already so in love with each other!"

Helen appears to be loving being a big sister already. On May 31, Ben shared a sweet photo of Helen leaning down toward her newborn sister. "This is a very memorable Memorial Day weekend for me and my girls," he wrote in the caption, adding the hashtags "#bigsgirls" and "#memorialmae."
