I tried to put his jacket on today and he has literally trashed the house. Pulled lamps on to the floor, throwing things at me. Has head butted me in the face and kicked me. My husband has taken him out while I put the house (and myself) back together.
That sounds incredibly hard - I’m not surprised you’re thinking disruption. He’s still very little, and totally not in control of his own behaviour, it sounds like something has triggered his fight or flight response (quite literally), while knowing that doesn’t help when you’re in the midst of it, it might help you think about how to make things feel safer for him.
I’d echo others, keep his world very small - even to having just one or two rooms that he has access to just now. Move breakable things out of reach, have lots of soft toys, cushions etc in the rooms hat he’s in so if he does loose it, he can’t injure himself or you. Don’t approach or try to touch him when he’s in fight mode, be with him nearby but having child proofed the room let him work it out of his system then be on hand to comfort him and talk to him. At that point you can help him make sense of his feelings, talking about how scared, angry, hurt etc he looked.
If he’s hitting you, it’s ok to gently restrain or redirect him - I’m guessing he was in such a state he was lashing out at everyone and everything. He’ll be terrified, and have feelings that are way too big for a little person to cope with and he’ll also likely regress to a younger age, so even less able to express himself.
Things that helped me in those early stages were not having a timetable where we needed to be anywhere so if they weren’t for getting dressed, or getting in the car, or putting shoes on it didn’t matter. We kept them very close to home, they too had a very busy foster home and really needed to grieve that loss and the grief took lots of different forms. We ordered shopping online, took turns in doing errands, tag teamed each other so neither of us were left on our own for too long. If there something you know calms him, do lots of it. My two liked water so spent long tines in the bath, going swimming, in paddling pools, the trampoline also helped them discharge the adrenaline in their system.
At the moment your little one is in survival mode, and so are you. Your entire world has turned on it’s head. In the best of circumstances you’d be wondering what the hell you’ve done - those feelings might be exacerbated by the challenges your facing just now. Your responses will be totally out of character because you don’t know how to do it yet, so feeling about for what might make it a tiny bit easier while thinking you’re doing it all wrong... not that I’ve been there.
Don’t listen to all the “enjoy your baby” comments, or to folk who don’t get how hard it is. It feels impossible at times - I remember thinking a few times that we might not make it, those thoughts are so normal. Access lots of support from people who will listen without judgement.
You’re doing such a fantastic job. It may not feel that way, but you are.
