Hi Joanna!
I think I'm gonna need further info in order to come up with a plan, cause yes, you're right, there were just so many changes and activities that it is very likely that lo is getting the grip of that and being restless because of that. But along that there can be a lot of development, teething, age-related issues that could be going on depending on how old is he and how his routine looks like, cause he might need a tweaking or even a total change in his daily routine that will fit with his new "life".
Meantime, try to take on some damage control measures in terms of going to sleep and dealing with night wakings. I recommend you to take a look at the FAQ's board at the top of this section in 2 threads, one called Teaching Independent Sleep and the other is called Most common Sleep busters. By looking at both of them you might have a clue on what's going on with your little one and choose a sleep training technique that suits your and his temper.
Keep us posted and good luck!
