Oh hun.sending you some hugs
sounds like you need them.
OK some of this could be developmental as well.As you know our LOs like to keep us on our toes!
i think it would definetely help to re-establish her routine (or as near as you can).on days when her naps haven't been great or even non-exsistent i would go for an early bedtime in the hope she will make the night time sleep up.
overtired babies can do well with an early bedtime (and it doesn't mean they will wake early) as the first part of the night sleep is their deep restorative sleep.
when she pulls herself up in her cot is she able to get herself down?if not plenty of practise at non nap times will help.Sasha did the very same thing to me at that age and turned it into a game
.what i did was just stand at the side of the cot not looking at her (or touching her) until she got bored and laid down to sleep.
if she is playing in her cot then i would be tempted to leave her and see what happens.unless shes getting upset i wouldn't intervene.you can't make them sleep unfortunately.i'd try not to offer her a btl either otherwise she'll expect it all the time to get to sleep.
personally i really think windowns are great as it sets the scene for sleep.my winddown for sasha was the same every time and usually about 5 mins.some los do better with a longer windown so its really what your baby prefers.
i'll try and think of some more ideas for you but hope the above helps.
