The TT closer to nature bottles do come with variflow - we used them with DD!
If she is finding PU/PD too stimulating then I wouldn't pick her up. If she is arching as you try to pick her up she is probably telling you she doesn't want to be picked up. I would soothe her in the cot with shh/pat - or if she doesn't like patting, rub her back or stroke her head instead. Rubbing their backs always works well for my two, and as they drift off I slow the rubs down and make them lighter.
It does sound as though she could be waking for the dummy or at least needing it to transition from one sleep cycle to the next (sleep cycles are about 45 mins) - it could be worth getting rid of it.
Is the 2oz at the DF a regular thing? If she is taking so little and taking a long time over it it may not be worth keeping up. Not all babies take to the DF - my two are prime examples
, we just stopped doing it and waited for them to wake. Even on the vary rare time they took a decent amount they still woke again anyway so it was easier for us to get an early night and just feed when they woke.
What do you think?
