Its not easy. But nothing worth having ever is.
As those of us who have done it will tell you, the best parent you will ever be is right now. Because the child you are imagining does as its told, loves what you love, eats well, sleeps well, wants to be your best friend as a teen instead of calling you a bitch and fucking off out with their friends.....
Its not what we think it will be, we assure ourselves that the reason other people are having a hard time is because they are doing it wrong. And thats a good thing because if we didnt think that the human race would have died out years ago!
I have had six children, so it aint that bad, and I would advise that in the main (assuming no issues with disabilities etc) the first three months are a mind numbing blur. Then they are lovely (although sleep can still be an issue) until they are 2 or 3 or 4. Mine never had the terrible twos but were beasts at 4...go figure. Then its plain sailing until abot 10 for girls and 12 for boys when they turn in to weird dual personality creatures. Vile, horrible, selfish and demanding one minute, and climbing onto you knee for a cuddle the next. The good news is that they become human again eventually!
The good outweighs the bad, definitely but when you are in the bad times, it doesnt feel like that.
The key thing is to make sure that you DONT get dumped with all the work. I of course advocate BF (even though I physically couldnt do it due to surgery) but I have to say that FF meant that there was no excuse for their dad to dodge out on nights, and making me the primary carer for ever after. I think that kind of thing can contribute massively to marriage issues after a baby comes. Daddy isnt physically needed in the way Mummy is so he gets to carry on as normal and by the time the baby is weaned off the breast he is used to doing fuck all and she is going back to work whilst carrying the entire family, house and mental load.
Get that sorted before you ditch the contraception.
Oh, and dont give up your job. Childcare is a shared cost, so it doesnt matter if on paper you are paying out the whole of one jobs salary, you need to keep that independence. If you dont know why, look at the relationships board for posts from women who gave up work to look after the kids and are then utterly fucked when the husband leaves, or feel that they have to stay in a marriage that makes them miserable because they have no independent income. Best case scenario, when the kids are older your career is still going well, so see it as an investment in your future, even if short term there is no financial gain.
