Most of the time last week we had 2 hr naps, yesterday he had a 2.75 hr nap and then slept from 8.30pm till 6am at night. However he only had one NW at 4.30am, which is great.
I have done some thinking and I have a new theory.
I was trying to figure out what changed when he started to consistently sleep shorter nights, and the only thing I could think of is that he started to have longer sleep stretches at night between his NWs. He used to wake every 1-2 hrs and in January he started to sleep for 4hrs at a time. Then I started to wean him and now his sleep stretches are anything from 4hrs up to 8hrs. So maybe he really is a low sleep baby and since he now sleeps better at night, he doesn't need as much total sleep anymore. I guess I can't have both of the good world.
I am just going to keep trying to put him to bed as early as I can and see how it goes. If he doesn't want to have longer nights, well then I guess that is all he needs. I don't think we can consistently have a BT of 8pm cause there is no way I can manage that. I will try for 8.30pm and hope I can keep it up.
Thank you for your help. I will let you know if we have had a change in mind and suddenly longer nights again.
