As to expectations:
I don't think there is any way you can really prepare someone for what it's going to be like to have their own child until it has arrived. So I think all attempts at expectation management are slightly pointless. Also, given that people's experiences, circumstances, and babies differ so much, I'm not sure that there is any useful way this can be done.
Starlight I'm finding your posts increasingly depressing. Instead of embracing the big adventure of parenthood and figuring it all out as we go along, you seem so keen to make sure we are all thinking the right way before we even begin.
I think I might be the anti-blueshoes - I did not expect to use a routine (I only found out about them on my ante-natal board on MN when people were talking in hushed tones about GF). All the babies in my family are what blueshoes diplomatically calls "high needs", poor sleepers, very hard work when they are small.
My Mum and all her sisters breasfed, some to nearly school age. The aunties all co-slept and when we were deciding what cot to get we kept getting told "I have one I used for my lot, well it's basically brand new " My expectation was that the first year or so would be mayhem, that we would get no sleep, and that LO would sleep in our bed.
I remember breaking the news to DH that our child was not going to be like his niece. I had never come across a baby like her - slept really well all night, very quiet and placid and easy. I explained to him that we wouldn't be getting a baby like that.
It didn't occur to me that I would get a baby like his family. My sister had a baby in July, and he is a much more cuddle, inward-facing, sleeps in parents arms baby than DD, but he too sleeps most of the night now. My mother is baffled. She thinks it's hilarious. (And also probably secretly that there is no justice in the world, if she now doesn't get to see our babies put us through what she went through with us )
If DD was like the baby I was expecting I'm sure I would be doing things totally differently. I'm doing things this way because this is what seems to work with her. This is how I've responded to how she is.
I'm simultaneously terrified that things I've done or will do will damage her and completely sure that they will. There is no perfect parents, there's just us, doing our best. I will never intentionally hard her, but I'm sure she'll grow up imperfect and I'm sure that I will have a hand in that. But I hope I'll also have a hand in all the great things I know she'll turn out to be and do.
I'm mostly trying not to sweat it too much.
