DH definitely does not want a second child, whereas I always imagined I would have two.
DS is 3.3 years old. DH was always scared of having DC and couldn't understand why anyone would want them. In the end he decided to go for it because he didn't want to lose me and thought it was unfair to "deny me a child" (I thought he'd decided to genuinely go for it). We had a moderately tough time with feeding issues, anxiety (me), very mixed up feelings (him).
At about 6m when I brought up a discussion about having a second he said "no way". From that point I started selling/passing on all the baby equipment/toys etc and got the coil. DH only started to bond with DS from about 9m and brilliantly that bond is great now, however I think DH struggles with the change from his old life (as do I, as do many people?!)
I always had in my mind about now is a last chance time to try to conceive a second as that would mean ~ 4 year gap and I would be just gone 35. So I am trying to come to terms with this and actually there is a part of me that likes the idea of the simplicity of just one but I have these huge emotional surges of wanting a second and enormous stabs of jealously when I see other Mums with more than 1.
Some of my issues are:
Am I not a good enough mother than my DH didn't say yes?
How to deal with all the questions from others. DH says tell them I don?t want another. 
Reconciling that it is ok to like babies and be involved with other babies if I don't have a second.
I have feelings of inadequacy at not providing DS a sibling.
Contraception choices going forward ? I currently have a coil but I am thinking of getting sterilised as I hate uncertainty and this is something I can "control"....
So much more I could say but don?t want OP to be too long. Probably more will come out if someone asks me the right questions.
Can you lovely MNers help me think through this.
