Sonny Bill Williams is being slammed over this family holiday photo

As we know, the internet loves to mummy-shame.

But now it looks like dads are also in the firing line.

Sonny Bill Williams took to Instagram to share a picture of his family on holiday in Rarotonga yesterday.

Captioned the photo “grateful”, the adorable snap features Sonny, his wife, Alana, and his two-year-old daughter Imaan.

But fans were quick to slam the All Black midfielder after noticing Imaan wasn't in a car seat.

"No child seat, are you serious?" wrote one follower.

"Car seat is needed for little ones Sonny, never travel without them," added another.

A third said: "I always fly with my car seats and they check them in for free with ever airline I've flown."

Others defended SBW, explaining that he may not have had access to a car seat.
