What a good boy! Selma Blair rewards her well behaved son Arthur with a sheet of stickers

He's fast turning from a sweet faced baby into an opinionated toddler.
But it's clear Selma Blair is already teaching her 18-month-old son Arthur the advantages of good behaviour.
While Arthur would no doubt have preferred to be playing at the park he put up with his mother rushing him between appointments in Los Angeles on Thursday.

And his good behaviour paid off as Selma rewarded her well behaved youngster with a sheet of pretty stickers.
Delighted Arthur immediately began playing with the treat, and even chose one for his mother to wear on her coat.
The pair were wrapped up warmly against the chilly wet weather, wearing matching knitted beanies.

Arthur is Selma's only child, and was born during her relationship with fashion designer Jason Bleick.
The pair split last August amid reports of endless rows, and have since been co-parenting their son.
But they were pictured arm-in-arm on Wednesday, sparking rumours of a possible reconciliation.
The 40-year-old actress had been dating Jason since 2010 but their relationship crumbled amidst the stresses of first-time parenthood.

The actress has made no secret of the struggles she faced in balancing new motherhood with an acting career.  

She told TV Week: 'Somehow I was just hanging on. But then it caught up with me – totally – and, since then, I’ve just fallen apart.
'I need to get myself back together so I can go back to work so I can pay for a house for this baby.'
