If your first was a bad sleeper, when were you brave enough to try for a second?

As per the title really! Our dd is now 21 months and finally seems to have figured out how to make it through the night more often than not. Torn between trying for number two to minimise the age gap or just enjoying a bur if normality for a bit longer. I'm 34 and dd came along pretty quickly but might not be so lucky next time...
Interested in when others with crap sleepers plucked up the courage to do it all again!

I like this thread, mainly because I had got to thinking I was the only one with a dc aged 32 months who has never slept through, or even nearly. On the other hand, reading about dcs finally sleeping through at 4.5 I am thinking...week!

Anyway, I am writing this on my phone tucked up between dd1 and Dd2 who is 6 months, so 2.2 years between them. And I know that between them they will wake me at least 6 times between now and morning, and that's if its a good night. But I am definitely in the getting it out of the way at once camp! The idea of getting a good night's sleep and then returning to this sleep deprived state once more seems far worse than just living through it now.

And whether there will be a dc3 remains to be seen

DS1 was a crap sleeper, didn't sleep through the night till he was 2 and after that had a very annoying phase of waking for the day at 5am!

DS2 is 12 weeks old and sleeps from 7 or 8pm till 6am with 1 wake up for a feed after which he goes straight back to sleep, no cuddling or rocking needed. He's even slept through 2 nights in the last week!

There's 4y8m between them, not sure why previous poster said there has to be maximum 3 year gap between children?
