Thank you very much Bec. That is the reason why I am getting frustrated - when I see her and do not know what is the reason and can not help her.
Regarding reflux - when she was little baby

I suspected she probably had it. However I never took her to paed to make diagnosis from one reason - in my country they do not treat it, it is consider baby will overgrow it (I am talking about mild type). She could not burp (it took us long time) and she was very frustrated when I would put her against my chest to burp, she would spitting-up very often, she hated tummy time. To make the situation more complexed - in addition to my strong let down I could never remove her from the breast in order to release that first miniwash

, or to burp her during sucking and continue to feed her. I tried many times but she was screaming and did not let my nipple and I could not do anything (she is very inpatient from the first day

). Another thing she was lazy to suck so after let down stopped she would stop to eat. I did breast compression and offered her two breasts... As you could see two of us had fun

but everything stopped when she got older - I think around 3.5 months and I thought we overgrew that. When you wrote about the milk supply and I read the text on the link you posted it reminded me on those days.
However in the last few months she did not show any signs of mild reflux (if it was in the past) - regular burping, no spitting - up.. What I could notice lately that she burps 4-5 times after feeding (completed) but then it happens also an hour after or even later. I connected that with lots of movements on the floor, rolling ... From developmental milestone I notice behaviour that is connected with the wonder week you gave me the link. In addition she is practicing a lot on the floor - she still does not sit up.
I hope that teething is the reason why she is so nervous, tired, screaming in the night -similar behaviour I have seen when she got first two teeth. Today I looked carefully into her mouth but nothing is swollen. O I forgot to mention that we also gave her homeopathy remedy chamomilla (day before yesterday and yesterday evening).
Maybe all these things together cause that... I really do not know...
Regarding EASY - today she woke up from am nap crying and very disturbed (my mother was there I was gone) and her diaper leaked. After pm nap she was in much better mood. I put her early in bed and I hope she will not start her EASY tomorrow at 5 am
