I don't think having a glass of wine would be too naughty but I know you'd like to have a couple of glasses guilt free.
You sound very stressed and I think you should show this thread to your partner. I was also very stressed and mine turned into PND, I'm not saying your depressed but I know how one thing can lead to another and it feels like your going out your mind. The small amount of time you get to yourself is like gold dust, you'd give £100 for half an hour to have a coffee in starbucks with a trashy mag.
If you could just get a couple of hours away to wander round the shops or go for a swim, even once a week. The child free time might make the need to get Ella onto formula less desperate and you might be able to wait another month or so and she could go onto cows milk at 12 months.
For the time being I can give you some other tips on how I got my dd to take formula. She never really took it properly but she would when she needed too, like when I had nights out or the occational Daddy day. There was a couple of times when I'd come back from a night out and dd would be desperate for a feed and totally refuse a bottle. I'd have to bf even though I'd been drinking, it only happened a couple of times but I felt so guilty.
My dd liked only SMA Gold premade cartons, she never had powder. To start with I tried bf'ing her, then popping her off and popping the bottle in her mouth. It only worked a few times. The best way was to prop her up on some pillows or cushions and stick on Baby Einstien dvd. This would only work if she wasn't starving and wasn't stressed at all. My dd liked the milk really hot, between 38-39 degrees. She would also take lots of breaks and we'd play peekaboo in between mouthfulls.
I had a friend who introduced bottles by giving them to her dd while she was pushing her along in her buggy. She seemed so shocked to be eating and moving she just drank it all up.
Have you tried expressing? Will your dd take expressed milk from a bottle?
There are quite a few charities out there who will offer a few hours free childcare. I used the Post Natal Depression Project, they looked after my dd for 2 hours a week. They are a registered nursery thats free. There is also the Scottish Parliament who have a free creche, you have to stay in the building though, I meet my friends in the cafe for lunch.
Sorry I can't help more. Are you going to baby toddler groups? I guess it's harder when you have an older one, people will just expect you to know everything already.
Phew, 2 years is a long time, can your dh help out more? Can he try to settle dd to bed at night? It might take hima while but she'll get used to it. My dh found it really hard but he hated failing and kept trying untill she went to sleep. He's no angel, I've only been out a few times, but he see's it as important that I have some time to myself. It works both ways, you both need time to yourselves.
Sorry, I've really spraffed on, dh is watching football and it bores me silly.
