Hilary Duff poses with her daughter Banks during a baby event... days after she was seen shooting her new Lizzie McGuire series

Her little girl is just 13 months old. And on Sunday Hilary Duff showed off baby Banks as they attended a party for  Happy Little Camper brand of natural baby diapers.

The 32-year-old actress held a fun garden party to celebrate the launch in Los Angeles. 

This comes days after the pinup was seen shooting her new Lizzie McGuire series for Disney+.

The party featured a band singing children's songs as the young guests shook tambourines and clicked drumsticks together in time to the music.

There was a shallow pool filled with blue plastic balls for the youngsters to play in.

A giant tub of soapy mixture with two people creating giant bubbles was also popular.

And guests were invited to stick their faces through a giant poster showing them as babies on a camping trip for fun photos of the event.

Gotcha: Banks stared happily at her mom after Hilary caught up with her to pose in front of her Happy Little Camper hoarding

Hilary shared a slew of snaps from the day.

And in one, she wrote this message: 'Motherhood has held my hardest and most rewarding days, which is why I’m so excited to introduce all the other moms and dads out there to my company, @happylittlecamperbaby!

'Safe and natural products shouldn’t be something you’re worrying about when you’re being a parent.'
