It is whether you feel they're worth it and I think you should really want it to try and have them - obviously unplanned babies happen.
No money ever again, no lie ins ever again, ruined body, less time and energy for marriage and friends... why do we do it to ourselves?
I have a 4 year old and we're not broke any more and I sleep plenty... body is mainly ruined by cake, not child rearing 
What are your thoughts? Do those of you who chose not to have DCs regret it? If you have DCs, do you prefer life with them? Has your marriage suffered?
I do love having my child but I underestimate the difficulty. We're struggling with the choice of having another, it's hard to convince myself to go for the madness that multiple children must bring, along with the being broke and no sleep!
Our marriage is happy. You have less time for each other though and your routines have to change to make it work, there was quite a long adjustment period for us after the initial firefighting phase.
If we unable to have children naturally, I don't think we would have adopted or gone down the IVF route. I think we would have had a happy life although we did always intend to have children.
How does your partner feel?
