I'm American, DH is British. It didn't even occur to me to bring my children up there. I was worried about all sorts of things, mainly health insurance and employee protection (esp maternity leave), plus how we'd pay for things like university.
Make sure you have cast iron health insurance and also look into your husband's employment contract. If he is on an expat package, I guess they'll look after you and you won't have the same concerns that a local would have. I forget what the terminology is at the moment, but essentially they can be let go with a week's notice. More senior people tend to agree longer contracts but these still need to be renegotiated after a period of time (many seem to be two to three year agreements.) But the protection is nothing like you would expect here. Don't even get me started on maternity leave (although not a factor for you.)
WRT health insurance - even if you have a good one, look into sick leave. I had a colleague who needed some surgery and he was going to be put on disability pay instead of full salary if he didn't get back in time.
It really is a very different mindset in that regard.
I mean - going over as an expat for three to five years would probably be a great experience. You will meet people from time to time with interesting views
to say the least. The thing that may affect your day to day life more than someone like Trump though is just the US as the starting point for everything, people are brought up to think it's the centre of the universe, which can be wearing.
The university I went to now costs $64K per year for room and board. My children won't be going to university in the US. If you're thinking of staying longer, bear it in mind that your kids may expect this to be a path open to them if their friends are doing it. A US school wouldn't have a clue how to help them get into a British uni.
