Help from some more experiences home providers please?!

I have a 12 month old on day 4 here. So far all is pretty much as you expect, perhaps a bit better than it could be. Decent sleep, eats, perfectly calm when held, ventures off to explore some but retreats when overwhelmed. He does scream if I am not able to hold him when he wants...but he deals with it and calms instantly when I can pick him up (which I balance with him being on the floor more than in arms).

My question is...at the table he eats happily if he likes the food but when he runs out of the part he likes he SCREAMS for more. He does not calm through talking or anything...just screams till he gets more.

I have 5 toddlers to feed, they all learn rather quickly that they wait until they are served with minimal fuss. They know they don't get repeated refills of one part of a meal. They all know that screaming does not speed up the food...in fact it greatly delays it here.

Today he was just screaming nonsense for more pork chop, making a normally enjoyable lunch time unenjoyable for my others (and me), so I cleaned him up and put him in the next room in a crib. I brought him back a short while later to try again, repeat...back he went. He is sitting between a wall and me so he is not overwhelmed by the other children being too close he just wants what he wants and he expects it NOW.

Is this acceptable practice? As far as I can tell it's just learned behavior that he needs to unlearn and I want it unlearned ASAP. Is it too much to expect on day 4? Should I wait until he is settled before being this firm?

He is only 6 weeks-2 months younger than all my others and they are able to ask and wait relatively calmly so I don't think it is too much to expect. They were not screamers to start though so just whined and that was easier to deal with when training them to wait. Should I treat the screaming like I did the whining kids and leave him at the table though? I am not worried about him going hungry as he still gets 2 bottles here that he doesn't finish because I feed table food first.

Is it ok that the crib is in the other room? I have video monitor of the crib. I could move a playpen into the main room where we eat. But if he's in the other room the other children can resume their meal a bit easier.

How many times would you bring him back to the table (I need to scrub him down and remove bib each time). I hope/expect that after a few days of this he improves.

When he is in the other room he screams, but it's the scream, scream, pause and listen, no one's coming scream, scream routine not a constant inconsolable panic.
