Thank you so much to everyone who replied, I really appreciate it.
I had an online session with a lactation consultant yesterday and he latched and fed, without nipple shields, for the first time, for the whole session.
But then in the evening latching failed again. I got him to latch in the middle of the night but I'm not sure it was a good latch, he wasn't swallowing much and my nipple was pinched at the end (my nipple is always pinched tbh). Then this morning my nipple shield had gone missing (how is it that things keep going missing when you have a young baby) and I had a meltdown, and my partner spent 2 hours trying to help me to latch, insisting that I don't need the shield, and the stress and pressure of it just sent me into meltdown and I'm pretty sure he's totally fed up of me now. He keeps showing me how Errol is trying to latch onto him, opening his mouth wide, he even latches onto Daddy's nose, but he won't/can't latch onto my breast. It's entirely possible my stress and unhappiness is causing these problems, I don't really know - my partner seems to think so - but his Dad saying how easy he would find it if he had breasts is just making me feel absolutely awful. I have just been crying all morning again.
Reading some of your replies I am starting to think maybe I should give up. Making up formula and getting it to the right temperature takes time, feeding the baby takes time, sterilising bottles and pumping gear takes time, pumping takes time, and at the moment I am just spending hours and hours trying to latch the baby, trying to get him to take milk from my breasts either with or without the shield and failing - and hours go by. I don't see how its physically possible to increase milk production, and to keep him fed, under these circumstances. Him being fed is the absolute priority.
Whether its stress or something else I guess it doesn't matter, if you're watching your tears falling down onto your baby because of breastfeeding, hours every day, maybe thats a sign that its not worth it. If I could feed him formula, know he's going to grow, and not be stressed about it wouldn't that be so much better for him? At the moment he cries all the time as he gets to such a state of hunger before I manage to feed him one way or the other, because I'm constantly trying to juggle finding different ways of feeding him.
At the same time it feels so frustratingly close that he latched and drank from my breasts happily and calmly for a whole hour yesterday when I was paying for a consultant.
Maybe I will try one more session with the consultant and see what happens, and decide after that. I'm someone who doesn't cope well with uncertainty and constantly flip-flopping about what the best course of action is is destroying me.
Thanks @Shefliesonherownwings for sharing your experience, it makes me feel so much better to hear about other mothers who have had to use formula and that it was the best choice for them. I would never judge someone else - I know for a fact that you will have tried your hardest to do the best for your baby - so why am I judging myself like this? It's not helpful.
@tmc14 thanks for your advice too, I think I do need to have a day off today. Perhaps I can just do some pumping and give myself a day off trying to latch him, perhaps I can go for a walk and just have some time to myself whilst husband looks after him. I haven't left the house in a week and I've not had more than 2 hours sleep at a time - both of which under any other circumstances would be clear indicators that you need to take a break!
