Judging from how he's coloured up in those photos, he's having a ball, and is very happy.
He's an explorer .... make sure you keep the room doors (the rooms you want him to stay out of) and the cabinet doors closed .... no deterrent to Rex (our big 3.5 yr old girl) who has a habit of opening kitchen cabinet doors (especially the corner pantry door) and checking out any gap she finds , we've found her under our double bed, behind the corner modular lounge , behind the TV cabinet, in empty boxes (the packing paper rustling sound gave her away) and between the Xmas presents (big pile of them on the floor for the grandson was irresistible to her).
I think you have a smart beardie on your hands .... means you need to keep an eye on him when he's going free range in the house.
I think our little boy (27wks old) Toothless is going to be a crazy beardie when we start giving him regular free-range floor time .... he's already showing how inquisitive he is about everything.
Meanwhile Peppa is more the snugglebug .... just like our big boy Puff was.
