I think she's starting her day OT from such a short night, do you actually start your day at 5.45am? I would have fed and put straight back down at that time, no A time or winddown as such ie treat as a night feed. What time do you ideally want to start your day?
By evening I think the OT has properly kicked in, hence the struggling to settle and appearing to want more milk. When babies are tired they will root because sucking is comforting, not because they are actually hungry (I think you probably realised that from your comment about her wanting more milk and not being able to take any). My DD was exactly like this at this age, I was often up until after midnight with her feeding on and off, rocking, cuddling etc until she would finally fall asleep in my arms and I could put her down in the Moses basket. It sounds like your first LO was a dream baby if he didn't go through this phase, but in my experience almost all babies do have unsettled evenings in the first few weeks and it is normal. Overstimulation will play a part, especially with an older LO around but there's not a lot you can do about that.
I know you are worried about independent sleeping and sleeping in the Moses, but I think few (if any) of DDs naps at this age were in there. If she did nap there it was because I'd held her until sleeping and then put her down, not because I spent time shh patting or anything like that. It's too much (IMO) to expect independent sleep at this age, LO has been carried and rocked constantly for 9 months so why wouldn't they need your help? It was probably nearer 3 months that she started taking more naps in the moses, but even then would often end up in the bouncy chair by the end of the day as she got harder to settle. I really think you will be able to enjoy this time more if you lower your expectations and do what you need to do to get you and LO some rest and be able to spend time with your toddler

. You will probably find that nearer 3-4 months it will be much easier to get LO into the Moses for sleeps (and she will learn independent sleep much quicker).
Don't forget as well that she has a potential reflux issue - and as I said in my first post if that is not resolved then expecting a good routine and easy settling really isn't realistic. I hope the Gaviscon starts to help x
