Hi kiansmam - (((Hugs))) - I don't know how much advice I can offer here, but can tell you that we go through the EXACT same thing. Sam's schedule is almost identical. We go through cycles where the WU is a bit later (like 6am after a 7:30 BT), but the past two weeks have been ridiculously bad. We've also had some NWs next week.
My DH laughs at me and it has become a joke because I am always saying it's because of Sam's teeth, but I really think it is...I don't know what else it could be. Is Kian teething? This has been going on since Sam turned 1 (on and off) and it was then that he started with his molars. He currently has all of the molars in (as of last week) and has one canine to go (which is causing major issues now). He is a very slow teether. I am wondering if this is what is happening with Kian? When he wakes, does he cry or is he happy in his crib?
Many people on here recommend a meds DF to get the teething toddler to sleep a bit longer in the AM. It hasn't worked for me because I can't seem to not wake him up when I'm doing it

, but it is a good idea if you can do it right (I am inept at it unfortunately).
I am hoping for both of our sakes that it is definitely teething -- because then at least we know there is an end in sight! (((Hugs)))
