‘Happy Mother’s Day to my best friend and partner,’ the 48-year-old Grammy nominee gushed in his Instagram slideshow.

‘Our children are so lucky to have you. Thank you for filling our home with love, laughter, and joy. I love you forever and ever my wife @kourtneykardash!’

On Sunday, Kourtney Kardashian Barker celebrated her first Mother’s Day with her fourth child – six-month-old son Rocky Thirteen Barker – who appears to have already sprouted a head of dark hair just like his famous folks

The 45-year-old reality star’s neighbor-turned-husband Travis Barker showed his appreciation by filling the grand foyer of their $8.5M six-bedroom mansion, inside Estates at the Oaks, with hundreds of white and pink roses

Travis posted never-before-seen snaps of little Rocky in his crucifix-covered baby carriage and a close-up of Kardashian squeezing his tiny toes.

This Wednesday, the Barkers – collectively known as ‘Kravis’ – will celebrate their second wedding anniversary in their usual PDA-filled, over-the-top style.

Also wishing the half-Armenian beauty a Happy Mother’s Day was her stepdaughter Alabama Luella Barker.

‘And to @kourtneykardash I love you, thank you [for] being another woman in my life to look after me and taking me in as your family,’ the 18-year-old aspiring rapper gushed via Instastory.

‘You have a such a passion for being a great mom and always showing out for all of your kids. Your grind is so inspiring. [You’re] the best!’

Kourtney reposted Alabama’s Instastory with the caption: ‘I love you so much!’

Barker also made sure to give a shout out to her ‘beautiful’ birth mother Shanna Moakler (whom the Blink-182 drummer divorced in 2008) as well as her two ‘amazing’ nannies Lizzy and Julie.

Kardashian’s other stepdaughter – 25-year-old Atiana De La Hoya – Instastoried a snap of her, Travis, and baby Rocky captioned: ‘The most amazing mom and stepmom to us all. Love you Kourt!’

Kourtney – who boasts 275.7M social media followers – Instastoried a video of the overwhelming floral explosion set to Louis Armstrong’s 1950 rendition of La Vie en Rose

And while the Calabasas socialite’s three older children with babydaddy Scott Disick aren’t on social media, she Instastoried a childhood snap with her momager Kris Jenner captioned: ‘Thank you @krisjenner for the best childhood I could dream of!’

‘Your body is beautiful at all stages — during pregnancy as we are glowing and growing, postpartum as we are healing and shrinking, and then that period I find the hardest as our bodies are still adjusting,’ Kourtney told Poosh last Wednesday.

‘And if you’re breastfeeding, that’s a whole other part of it. I try to be kind to myself as my body finds a new normal. The pressure put on us to bounce back when everything is new and different isn’t realistic.’

Kourtney undergoes ‘urgent fetal surgery’ in the 10-episode fifth season of The Kardashians – premiering May 23 on Hulu – which she also executive produced with her famous family.

Kardashian was technically the first member of her family to star in a reality show – The Simple Life-inspired eight-episode series Filthy Rich: Cattle Drive, which aired in 2005 on E!

Travis doesn’t resume Blink-182’s 91-date 2023-2024 World Tour until August 23 with a concert at the Little John’s Farm in Reading, England.

It should give the married couple ample opportunity to bond with their first child together.
