Not going through it, but have been: ds1 (2y, 4m) was result of IVF3, and ds2 (3m) the result of IVF4. So I was lucky that it worked first time second time round.
Childcare was definitely an issue during treatment, especially as ds1 wasn't keen on just being left with my friends, and I needed to be coasted as I was at risk of OHSS. I must admit though that I did in some respects look forward to the day of egg collection - having an excuse to be in bed most of the day (my hospital does general anaesthetic) was great!
I guess that I always hped for more than one child, and so the decision to start treatment again was based on the fact that it might take several attempts again, and so I didn't really feel broody - it took several more months for those feelings to kick in.
And like you I assumed that I would be more matter of fact about things. In some respects I managed this, as I never had brilliant cycles, nor good quality embryos - nevertheless I had been successful before. It is hard not to focus on how many follicles you have at what size etc, but I just had to remind myself that it hadn't really been a good indicator previously as to the outcome.
I was an awful lot busier as well with the toddler to look after - this helped. All the best with your cycle.
