Willow, hun, Michelle is right , there are no rules. If you try to follow rules at this stage you will just send yourself around the bend! Babies change all the time, that's one thing I've learnt. Just when you think things have settled, something happens and it all goes out the window.

I hear you on the one sleep cycle thing, and I would be lying if I didn't say that sometimes it drives me insane too (I know you've responded to my posts about it LOL). But TBH, life is a lot easier when you don't stress about it, and just follow their lead. Maybe that's all the sleep your DS needs? He's still only little, things will change, and change again, many times. TRY not to stress hun, and just enjoy your little boy. And remember, when you get that sinking feeling when you hear him stir after 40 minutes IT WON'T ALWAYS BE LIKE THIS!
