It's a little freakish at first, I agree. We so wanted to have a baby; but during the first week, I started crying one night and said to dh, "Do you REALIZE what we have just DONE?!!!....We'll worry about her the REST OF OUR LIVES!!!!!!"
I don't think there is any magic formula in gettting through the 'shock' of having a new baby; but the want of having it overcomes the lack of sleep, the worry about immunizations, the dirty diapers, etc.
I had to remember that the action of living meant that 'everything was subject to change'. And, so it goes even today. You just learn to 'go with the flow' and relish the moments you have.
In your case, the moments and memories you WILL have. Reading specific books will help, I'm sure...but the bottom line to me is that parenting is mainly putting someone else before yourself. During 'babyhood' is the paramount time for this in many ways....but there is a wonderful payoff called 'family'.
Sincerely,
Linny
