As the others have said - I wouldn't fully trust my oh to choose an area, house, school without me being there. We are leaving on the 3rd July and are in the process of sorting through the house - it's by far the worse bit for me and very stressful. Organising letting agents, removals, tip/charity runs its a lot to do with two kids and working full time. My kids are 5 and 2 years and haven't really noticed the stress, their life is exactly the same, school/nursery, going to the park, supermarket etc they are both really excited about our new adventure. I'm glad I'm a team of 2 doing all of this not on my own. My kids so far have been very resilient to the changes around them so far and I'm sure it will continue.
We we have a temp accommodation for the first 8 weeks while our stuff is being shipped over, it means we are choose a new home together as a family.
Good luck
