Hey PicknMix.
Having a baby really is a life changing event and no one can stress to you how much so. However, it is the best thing that has ever happened to me, yes it is hard work, but as Natty says, the pros heavily outweigh the cons.
Me and DP decided we wanted children at some point but both our babies were happy little accidents (I should say gifts from God) and I wouldnt for a moment have had it any other way.
DP is the only one in our relationship that works, we have no savings and he only earns roughly £200 per week... Our babies don't want for anything. You don't need half the things people tell you you will. Just a few sleepsuits/baby grows, somewhere for them to sleep, pushchair, bottles (steriliser is an option not a necessity, pan of boiling water does the same thing) nappies and cotton wool, and when they are about 2 months old get a play gym. Before 6 months feeding them only costs £6 per week, unless you breast feed of course, then its free, something I have failed to do both times, but hey, thats life.
I really feel, as someone who was trust (not entirely unwillingly) into motherhood that no, there is no right time. Whenever it happens you will enjoy it because they bring out a part of you that you wont have used before and you will love that you can cope and that you know what is best for the little alien in front of you.
It is not easy, no one says it will be, but it is the most rewarding thing I have ever done. I dont miss pubbing and clubbing and I dont care that my friends rarely come to see me anymore, because the people who I really like spending time with are now my children.
Yes, it is life changing and no, there is no right time (see now why couldnt I have just typed that in the first place?! lol)
