Laura's fans thanked her for her realness and couldn't help but compliment her on her gorgeous little family.
"Congratulations Laura!! Beautiful girl gang," one wrote.
"I love your honesty Laura 👏. What all expectant and new parents need. Keep it up!" penned another.
"Love seeing real motherhood on Instagram 💞 so very refreshing and delightful. What a gorgeous bunch," remarked a third.
Proud dad Matty J also shared some footage to his own Instagram account of his three gorgeous girls.
In a clip posted to his Stories, Laura can be heard asking an excited Marlie if she wants to hold her baby sister to which the cheeky toddler couldn't refuse!
The former Bachelor also shared a snap of Laura, Marlie (lactation cookie in hand) and Lola cuddled up together on the couch and sweetly captioned it: "My gals..."
On Thursday, Laura and Matty introduced their second child to the world via two heartfelt Instagram posts.
"Welcome to the world my precious little Lola Ellis Johnson," Laura penned in hers.
"I said I would eat my own poop if you were a girl, and yet HERE YOU ARE! Already teaching me the worldly life lessons that come with being a mama - such as, just because I feel something to be true (in my waters) doesn’t mean it is and not to make promises to @matthewdavidjohnson that I 100% do not intend on keeping.
"You are perfection. You are dynamite. We love you and your 95 percentile head endlessly."
Meanwhile, Matty wrote: "Lola Ellis Johnson.. you had us all fooled! Everyone from your Mum, your Nana, the neighbour and even the postman thought you were going to be a boy. Playing pranks on us all already.. I love it! I also love that I’m now well and truly outnumbered by three beautiful and rambunctious girls at home. Welcome to the family. ❤️""
