Jenna was a shocking napper during the day. The best sleeps she would have were in the sling.
When she started going down regularly for 2 naps a day (I guess about 5-6m??) all of a sudden things started to change, and we used to get one long sleep, one short sleep.
Then when we dropped to one sleep she turned into my marvellous 1.5-2.5hr napper during the day.
Nights are still challenging on occasion, but I do agree that there is nothing you can do but live with it. It sucks - but thats having kids I spose.

I hope the sleep school is able to help you some. It would be great for you to have some reassurance that you aren't doing things "wrong". But just remember - if you aren't comfortable wiht what they are telling you to do, bubs will pick up on it, adn their techniques wnt work anyway.
