Up and down the stairs

Today, daddy needed to go SingPost so here we are at a Post office past its opening hrs....while daddy pays his bills, here's the little one trying to go up and down the stairs ON HIS OWN....well he has always loved playing with stairs and today is the 1st time mama sees him wanting to go up and down on his own...looks quite dangerous when he's going down coz if he loses his balance he might just fall fwd...well a time to 'thrill' him while waiting for daddy...see how he 'rejoices' when he got up the stairs and down the stairs as well (of coz with mama cheering him)
