My DS2 is 10 months, been an amazing sleeper until now (unlike DS1 who is almost 5 and still doesn't sleep through the night...), but is suddenly not sleeping well... and i am just trying to work through why... at the moment he naps 9.30/10-10.30/11ish, then again 12.30-2ish. Can't remember when they tend to drop that morning nap...
