hey Meg,
Could it be a growth spurt? there is a major one at 6mo i think? Alexa often seems more tired when having a GS (tho that would only last a few days i guess?) its weird cos when Alexa seems to have extra tired days and like u say, can only do around 2h20ish, i am so puzzled, so its still not consistent. but then maybe they get tired more for no other reason thn they just are??! (iykwim?). i think my DP thinks i am a bit mad, when i get stressed about it and say "she cant be going backwards!" he thinks i am looking at her like a robot that should do exact same times every A time, but thats how its worked before isn't it??!
one of my fears is that when she has a more tired day and i try and keep her going for longer and we tip over into OT i then have to resort to AP'ing which is a danger i guess! I cant listen to her cry for a minute so when i know its not mantra i'm right in there, and sometimes have to go back to swaddling her arms or BFing to sleep...
All4Love have u tried swaddling maybe just one arm? i know when Alexa is OT or OS hr arms get so jerky they really stop her falling to sleep. and as Meg said... WD is crucial for us...
