I personally don't think anyone was judging, it is just that when someone doesn't express the same opinion it is considered judging.
I also, find expressing more hassle than it is worth, I still have to spend the time doing it, when I could be just feeding the baby and then using hubby to entertain bubs when he is home. While I have my shower/break what ever.
That said I don't give two hoots if someone wants to bottle feed.
But I don't think in most cases it is the bottle that is the problem or the teat it is just the fact it isn't the breast. People say they tried heaps of bottles until they finally found one that the baby would take. Baby most likely got to that last bottle and thought yeah why not I will take the milk I am thirsty enough today, bottle having no bearing on the situation could have been the very first bottle being used again it wouldn't have mattered.
To the OP, your poor friend is probably shattered and with a baby at 2 months they will have been feeding constantly which I think gets even the biggest pro breast feeders down, it will pass........ it just doesn't seem like it when you are in the situation.
If using a bottle is what she wants to do just get her to keep trying, not keep spending money on lots of different bottles.
With regards to the shower, I use to put bubs in the bathroom with me. Heck I have two kids now and another one on the way,
I can't remember the last time I had a shower or used the toilet when one or both kids didn't come in and ask something very very important
