How many kids an ideal couple should have?

I have a family of four including my parents,my little brother and me.Brother is 4 years' younger than me. When I was a liitle girl,I didn't like him, because I had to share all with him. As I grow up , I feel I am much happier than those classmates or friends who has no brother or sisters. Maybe because of him, I have a more partner to share things not only material but also spiritual. I'd like to tell him my happiness or sadness. So does he. So I also wanna have a family like this after I get married as long as I can support them. But it seems to be impossible here now. We have to consider more things and make sure they can have a good life arter they are born...

Yes probably two if its a 1boy or 1 girl, but for me i prefer 3 or actually more as long as i make sure i can support all of them. Were 4 siblings and its a wacky one, its nice to have a big family.

I want to have more, maybe 3. On the other side I'm worried I can't give them the same amount of care. I don't want my kids think I love one more than the others. Let's see :)
