Hi Pippinn
Can I start by saying that I too only have one ds (11months) at the moment, and have had the "when for the next one" conversation with my partner several times, and each time we come up with something different.
We are getting married in 2 months so it would be totally impractical to even contemplate it at the moment - but would definitely like another one one day!
Anyway with regard to your concerns:
I couldn't possibly love a 2nd as much as DS (although I'm sure most mums think that).
I've heard a lot of mums say that, yet in hindsight they cannot believe they said such a thing, and love both children equally once the second one has arrived.
I have only recently returned to work (part time) and it might piss them off a bit.
I really wouldn't worry about work - I know someone who went back to work after 6 months, only to discover she had accidentally fallen pregnant whilst breastfeeding, and was already 3 months pg on starting back!! Her work was fine about it. I suppose it depends on the employer, but I really wouldn't even consider their feelings when making this decision (sorry if a bit harsh!)
I won't be able to cope with a 2yr old and a newborn - how do you even leave the house?!
My friend has 2 boys and they are exactly 2 years apart - she was worried how she would cope, but she had a lot of support from family, and her newborn was so good compared to what her first born had been like that she found it a breeze! I think it all depends on what sort of a baby you have. If I had another like my ds when he was newborn, I think I'd have a nervous breakdown. But of course you can't know this in advance !
It's all really nice and (relatively) easy with DS now and I don't want to mess that up and make life harder for myself.
I feel exactly the same - I would love another baby as I would really like a girl playmate for my ds, but like you I am quite content and feel I am just about coping to look after myself, ds, dp and get the housework done!
It would be such a shock to the system!
I think as well there are other factors such as what sort of a birth you had - apparently if you have had a c-section, you should wait at least 2 years before trying for another.
My sister and I are 20 months apart, and a lot of people my age have around about that age gap between their siblings. To me it is sort of the norm, although nowadays from what I can see, a lot of people are leaving bigger age gaps.
I had a fantastic relationship with my sister and we used to play together so did not demand a lot of my parents attention (another bonus!).
I think I started a thread on this when I was feeling broody a few months ago - I'll see if I can find it and link to it as there were some really good replies.
Hope that helps and is not too confusing!
