I think the idea of ebf is often a lot more lovely than the reality - to be honest if you had a good latch in the first few days and found it was going well in hospital then wow - that’s actually amazing in my limited experience! Breastfeeding is I would say 50:50 learned skill and innate instinct. Your baby is learning but actually so are you.
Double check your baby is still latching properly - a lazy latch can cause wind and slow feeding.
Being at home, please don’t discount the flood of hormones, the exhaustion and the fact your life has been turned upside down - breastfeeding is extraordinarily time-consuming at first. Young babies will cluster feed, you kind of just have to let that happen and recognise it’s normal and many, many EBF mums feel like you do at some point - overwhelmed, touched out and quite depressed about it.
Go to the local bread feeding clinic or talk to HV when you weigh in, or go to a mum and baby group - you’ll get a lot of reassurance and encouragement and sympathy and help (if needed).
And then at some point (maybe several months further along) you may find it is just so easy - you recognise your baby’s cries, you’ve learned when baby is just sucking for comfort (which is not always the worst thing in the world but no one wants a baby latched on 24x7!) and you can unlatch. I found bf so convenient when I went out with friends and on vacation but that was later.
The early days are hard, hard, hard. There’s absolutely no shame in switching to a bottle - but don’t assume you’re somehow failing (or alternatively 90% of breastfeeding mums I know have been failing!)
