hi, what do you want to do? if you could take away the problems of bf then would you want to continue? if yes then get yourself seen by a lactation consultant, call lll for advice. the midwife isn't right, gaining weight doesn't mean no tongue tie, it just means hes managing to get enough, but at the expense of your nipples. your clearly identifying problems eg mouth not opening wide enough and tongue doesn't protrude (sign of tongue tie, even if only partial, if they cant move their tongue properly then the nipple is going to get the force of those movements) so sorry but it sounds like you've been a victim of rubbish advice. also 6 weeks typical recommendation for bottles but many do use before that just fine. also, nipple shields are slightly different, they aren't confusing in the same way a bottle is because its still from the breast, they still have to suck the same way, the issue is usually supply. however if you think your supply is pretty good then really its your choice, but to me if its a toss up between giving your nipples a break but being able to continue feeding but risking a drop in supply or the alternative is continue=ing in pain until you stop then id try the nipple shields (ps I used nipple shields from day 3 for inverted nipples, sure it added some problems but it solved others, we got off them after a few months when her mouth had got bigger and she got better at latching, and she natural term weaned, so it all worked out in the end) also, expressing is still breastfeeding, and its a very valid method. there are many women who exclusively pump, its just not exactly easier as essentially youre double feeding if that makes sense, but I have a friend who happily pumped until 8 months. really depends on how you respond to pumping.
really you have to make your own choice, but make it an informed one. at the moment it sounds like you've not really had any advice from people who actually understand breastfeeding. breastfeeding isn't easy, and initially it can be painful, and unusual and it is very demanding, but that's not what youre describing, what youre describing is unbearable pain, noticing things that aren't right, a distressed baby and no support. those are things that can be changed. hope you can find support. also, nothing is set in stone. eg, if you are at breaking point then try pumping or nipple shields, or even a bottle, sometimes just realising that whilst everything that's said is true about confusing babies etc, it is also not something that happens just like that and not something that has to mean the end of breastfeeding. it makes me mad when I hear professionals behaving this way. the goal should be to help women continue breastfeeding and that sometimes means being flexible. for goodness sakes they forced me to use a bottle at 3 days old for top ups, she did get confused after a day, and so I switched to one bottle at night, that she coped with fine. I wish I hadn't listened at all, but it did make me understand that babies don't just suddnenly stop being able to feed. if you are in excrutiating pain for example in the middle of the night and want to give a bottle make a decision to do that, then you can face the rest in the morning, get up, call someone more knowledgeable and get help. hope that makes sense? do what suits you, if that includes bfing in some way then get some help, and go easy on yourself, there is a huge grey area between exclusive feeding and formula feeding, and many many people fall in there, all breast milk offers benefits, increased if exclusive but huge benefits with every single feed, so iftheres a bit of both, then that's ok too.
