Thanks a lot for the replies. I'll try to answer the additional questions and explain myself some more.
We are from Belgium. And indeed I'm focussed on the benefits now. Not because we want to profit from the Finnish system but to get an idea. My husband will have to formulate how much he wants to earn and we want to get about the same as we have in Belgium. But in Belgium I also get some money (about the same: 300 before taxes) because I stay at home for the kids and I probably won’t get this kind of allowance in Finland so we have to think about this as well.
It is true that he will have a decent job but I also think that living in the Helsinki area will be a little bit more expensive then where we are living now. We know that we have to pay in advance, that we have saved up already. (Luckily

) And paperwork won’t be a problem because I know some people living in Finland that will help us out with the paperwork.
I don’t want to burden them with all my questions though so I wanted to get an idea myself before I started to talk to them. We’re going up to visit them in a couple of weeks and I’m looking forward to that!
I’m not expecting to get unemployment benefits myself but I was hoping that healthcare and such would be taken care of. (I’ll read on the Kela page some more for these matters)
Putting my kids in daycare however is something I don’t wish to do until they are at least three years old. That’s about the age when they go to school in Belgium and I could live with the idea of sending them to daycare around that age in Finland. I know that the Finnish system is different so I was already thinking of how I could integrate without having a job: in Belgium you bring your kid to school, see the other parents, do stuff around the school, … and you can make friends like this. But seeing as kids only go to school around the age of seven, this will be rather difficult in Finland.
IF I would put them in daycare: Where can I read about that? Do you get a choice? Are there different kinds of daycare? Do they have a lot of openings? Is there a waiting list? And also: how much would this cost (approximately)?
I know that I have to find a place for my kids to go too. I was just thinking about it the way I know it: school at age of 3 – not 7.
After reading my post through it kinda occurred to me you must think I’m some kind of golddigger or something. Please know that this is not true. I KNOW Finland owes me nothing expect for maybe berries when I go out to pick them

. If it where me, I’d move in a heartbeat. But I don’t want to end up living there and then having to come back to Belgium in 6 months.
My reasons for coming to Finland you ask? Because I fell in love with it! School system much better than anything I’m used to, language much more interesting, nature pure, seasons more attractive, … and of course: Joulupukki

. I could go on for hours.
My reasons for being reluctant to come: I like what I have in Belgium as well: I work as a volunteer for La Leche League and I’m in the board of an organisation that makes it possible for mothers to come together with other mothers and their small kids with focus on attachment parenting. I’ll miss both of these things a lot if we move.
I wanted to write a lot more but my kids need me right now. You can expect me back soon

.
Thanks for your time though! I learned a lot already.
