Wow - thank you to everyone who responded.
To everyone who said 'it's simple, you just don't want them' - I can see your point, because this is a complete unknown to me, but I really am undecided. I would have no problem admitting that I don't want children - in fact, for years that's what I have told my mother. But lately I have started to think differently - admittedly it's all over the place, sometimes I think I want one, then I am not so sure again.
Before, when I saw kids out and about, or screaming on an aeroplane I just thought they were annoying and couldn't ever see myself with one. Now I find myself watching them and imagining being their mother and how I would adjust. Once or twice when I come home from work and my partner isn't yet home, I visualise in my head what I would do after work and what our new routine would be.
To the person who said I would struggle to find only children who were happy about it - I am an only child myself and I was perfectly happy growing up. Though I was shy I soon grew out of it. I get on great with my mum, she bought me up alone with a help from my grandparents who helped out with the school run etc while she worked full time.
Rioja123 - It's not that I am trying to talk myself into it, so much as really wanting to think this through. Obviously my lifestyle the way it is now, is all I have known since being an adult so it's hard to know what I would be like as a parent.
seafoodeatit - I agree, I have written several pro/con lists but it's completely stupid! I can't make a decision like that from one of my many lists!
theiggorcist - I am aware of that book and several blogs like it, which show me it is possible. But I can only imagine how much things will change when travelling with a baby/child. It's tempting to borrow a child and take them with us to see how we cope!
I do have several friends who are pregnant right now, which I am excited about as this will give me a bit more exposure to babies/kids, and might help me to make a decision. I have spent no time around babies at all, so it's all very alien to me. Older children I have a little more experience with, and I don't struggle to know what to do with them so much.
Is it really true that the majority of people immediately know if they want kids? I am a huge over thinker about pretty much everything in life, so it just be my personality. Obviously I would hate to rush into a decision and regret my choice. I can see myself with just the one child - then we can dedicate our time, money and effort to them, and ensure they have plenty of activities where they are around other kids.
It sounds so very shallow, but the travel thing is a big deal to us. However, maybe that won't even be on our mind afterwards. It's not like we will never have the option again, my boyfriends mum doesn't work and both of our mums will be dying to help out, they have made that very clear. I am sure when the child is old enough we could get a long weekend or week away on our own if we wanted a little break.
I am also aware that once the decision is made, that's it, obviously we will always be there for our child even when they have moved out and left home. Travel may be somewhat important, but I think I would have no problems giving up nights out, alcohol, eating out regularly and some of our disposable income. We are trying to become a bit more minimalist anyway and stop buying ourselves things that we don't really need.
I would like to bring my child up to value experiences over things, so it's likely we would budget for more holidays, and not drown them in more toys than are necessary. I admit, one of the reasons is definitely for our parents to have a grandchild, but I would never let that make my decision for me. I just know they would be great, and very involved.
I might be putting a bit too much pressure on myself to make a decision, but with my fatigue at the moment, if I am going to do this it has to be while I am youngish, as I get older I may find I have less energy and struggle more with everything. At this age, and if we only have one child, I could go part time if we wanted to. If we really needed to we could survive comfortably on my partners salary, especially if the travel was to go.
I think while the child was small, we would probably be fine to compromise, (obviously no diving! and limit the travel, or maybe even bring our parents along!) and maybe figure it out as we go. I just don't know, it's not like you can do a trial run! It's weird that this is weighing on my mind so much, it's like a switch has been switched since finding out some friends are expecting, as it never been on my mind until the past 8 months or so.
This is getting rather long and I feel as though I am going around in circles. I am not sure what else I can do, or consider, to help in making a decision. Sure, we would probably be just fine as we are right now, but when we are older, and we don't have much family left, we may well regret our decision.
