I don't think that you should put the things you want to do to one side, i think if i did that, i would be very resentful, and feel like i had done the wrong thing by having a baby.
I'll just have finished the 3rd year of my degree when I have the baby, and I fully intend to go back to do my 4th year, full-time, as its the only way I can afford to do it. The uni will just have to be flexible for me and my OH so we can both do this.
Sure, me and the OH wanted to see a few more places in the world, but apart from financial reasons, there are no reason why we can't do this - plus after we both have our honours degrees, and hopefully masters, we can get good jobs and not just provide a good life for our child, but for ourselves as well.
I'm not prepared to forget all my ambitions because i'm having a baby, and i'm not prepared to forget who I am either. I know that this will be difficult, and I don't mean by any length that I wont put my baby first, but other things have to be important too, if you know what i mean!
sorry, this has turned into a story!
