Ah, only here 3 weeks ?
Well, the poor boy has got an awful lot to cope with then, hasn't he....not least being expected to live with someone who is a virtual stranger, let alone sleep in the same bed !
Reading your original post again, I find it rather concerning that your partner is SHOUTING at the boy.
Obviously there are bound to be stresses and strains in the household, but at this time I think you and your partner need to concentrate on attending to the needs of your very young and vulnerable child.
Is there a room that can be used as a bedroom for his exclusive use ?
If so, it needs to be made attractive to him, a comfortable and secure place, where he wants to be. I would buy a large stuffed 'guard' dog for instance, one that is going protect him from ghosts etc.
For my own boy I built a bed very similar to this one for him...so that going to bed was almost an adventure, and very much his personal space. It didn't cost me much money...just a lot of love and time.
I also made go-karts for my kids and other stuff to keep them amused. That's what dads are for !
