Sorry to laugh - this just made me smile! Maybe Spring Watch needs a watershed.....!! 😂
It sounds as if Reese is well socialized, so I think this is just a normal reaction to something he can't quite understand, Do you have a big televison? I can imagine, from his point of view, the images could be a bit scary, especially as he probably doesn't see them quite like we would and he's not to know the noises aren't "real".
I don't think I'd stop watching, - he needs exposure to as many different things as possible for his confidence to continue growing. I would just reassure him its ok but without making a big deal of it - like you've been doing with the branch etc..Maybe entice him a bit nearer to the telly, so he can see its nothing scary and then play with him or tickle him, to make it see its pleasurable and nothing to be frightened of. Main thing is not to reinforce or reward the fear by over comforting him, let him retreat if he wants to, and don't force him, to just try and stay as natural and upbeat as you can so he'll learn that its normal.
I think its quite normal at Reese's age, its a big world out there (or in here, if the telly's big enough!

). The more situations he's exposed to, the more confident he'll become and it won't be long before he's mastered the remote control! 😬😬 Good luck!
