Hi everyone, I've had good advice on this board before so your input is appreciated 
DS is 8mo and until now has been on three naps. He's at nursery during the day and usually naps in the early morning around 8ish, then again twice before I pick him up at 4. He was napping about two and a half hours total until this week and then going to bed around 6/6:30.
Then last week he started crawling (don't know if that's relevant) and we started picking him up at 2 so he hadn't had his last nap yet. But he wasn't tired until about 4, which was a problem because obviously his bedtime then got pushed later.
Last night he eventually went for a nap at 5 (he was exhausted). I fell asleep too
and, aside from his usual top up feed at 10, he slept through til our usual wake up time (we all get up for work at 5:30/6am).
Today as an experiment I kept him busy from pick up time at 2pm til 5 and he has fallen fast asleep, at 5pm, within about two minutes! Usually it takes ages to settle him. He was in a much better mood today as well than he has been recently.
My questions are:
Should he be moving to a two nap day now?
Is this a sign that the third nap is being dropped?
Will he always want to go to bed at 5 if he has two naps? Does that sound like a reasonable bedtime? It makes me a bit sad because I won't get much time with him - but will his bedtime get later again soon?
