Hi there! I'm new here, so please bear with me.

I'm a British citizen, currently living with my American husband here in the states. We have a 6 month old baby and we want to move to the UK. My husband has a very well paid job here and is hopefully getting a job in England soon. We are coming over for Christmas and he is having an interview with them then, but it seems promising already that he will get it.
So I have started looking into the visa process, as this was something they asked him as to how long it would take. Right now it looks like the processing time shows, 100% are done in 2 months. So here are my questions...
I have been reading about a spousal visa, but I can't find anything with that name. Is it in fact a settlement visa we will need to apply for for him?
It says that he needs to have £18,600 income (Am I reading that right, its the US citizen and not the British one?). Right now in the states he has more than that, but until he gets offered this job he won't have it there.
Would a statement from his earnings in the US be enough? Or would he need a letter from the new employer too?
It also says about a sponsoring child. When we come over at Christmas, I was planning on getting her her british passport anyway, before this job opportunity came up.
So would we A: Need to put her on his visa application like it states, and B: Need to have the extra £2,400 to show for her?
I'm confused about that whole child thing. If one parent is a citizen, then surely, getting her a passport and giving her citizenship, is easier than adding them to your visa and getting the child a visa too?
Please tell me if I am wrong about this. This all seems so complicated, and I had to go through the whole US immigration to get here! Maybe its just the way its laid out and my brain can't get around it!
Thanks for your help
