I used to dread my LO waking for a feed in the early weeks. His feeds used to last 3 hours, then he would sleep for an hour and then be back on my boob. It was hellish. Plus I had lots of stitches and the worst urine incontinence problem (I kid you not and its still ongoing) and my LO was a very demanding feeder. I then developed a nasty abcess at the base of my spine to cause me even more pain. I survived the first 10 days on about 20 hours sleep total. Goodness knows how but I did. OH went back to work 4 days after he was born. I had no energy, no pleasure, no nothing in breastfeeding in those early days because of everything that was wrong. I coped simply as I knew I had to and believed it would get better as my health improved. Yes my LO was latching and feeding but I was a wreck. That often seems to be the way with new mums in the early weeks, regardless if they bottle or breastfeed.
Bit I did tough it out and it was and is so very worth it. I really felt I could and would overcome the problems if I stuck with it. I never considered switching to bottle feeding. I did express a few feeds around 3 weeks for OH to do on advice from HV but tbh it didn't really work for us. So went back to BF'ing it all. And its been that way ever since.
FWIW bottle or boob it'll be tough for different reasons. If you wanted to breastfeed I'd say stick with it as it does get better. Many of us successful breastfeeding Mums have had hellish early weeks but will tell you they are glad they persevered and they got there in the end. And yes, there are others who switched and are happy with that also.
If your LO were losing weight (they usually do in the first week regardless) and not gaining after then maybe consider bottle, but before that, try the old 24 hours in bed with baby, lots of skin on skin, let him feed whenever and stick to the boob and stimulate your supply. I find now if my LO cries my boobs start leaking. Something in me kicks it off
Have you tried talking to a BF'in counsellor? They can advise about any problems you are having with him latching or staying on your boob etc. Might be worthwhile exploring your options in the next few days before giving up totally and going over to bottle. There are people out there who can help you and advise you far better than your MW appears to have done. It may be that if you have been feeding your LO expressed breast milk (I read elsewhere you were planning on this and may have done so) then he has nipple confusion and simply finds a bottle easier so fusses when given your boob. Special slow flow teats are advised when breastfeeding and expressing so they have to work to suck the milk from the bottle and therefore not get lazy when back on your boob. If the flow from the teat was too fast and your LO didn't have to work much to get milk he may well fuss and be awkward when given your boob. And again why it's advised to solely BF for the first 6-8 weeks to help establish everything and prevent problems.
Please be certain going over to bottle feeding is the right thing for you. And that you have explored and tried all the options before giving up so you don't have regrets later.
I know every person is different, and what works for one won't for another, but I am proof that hellish early weeks for any number of reasons can still mean successful breastfeeding.
