I'm feeling so deflated today. Baby is  5 days old and the midwife came to weigh him and he's lost 8% of his weight. She said up to 10% is ok but they're coming back to weigh him again the day after tomorrow. I showed her how I've been feeding him and she said I'm not latching him on well enough, but she couldn't get him to latch on either, then she said he should be sucking differently than he is doing but there's nothing I can do about how he sucks. She said I should continue as I have been and hopefully there will be an improvement but I just feel completely useless and like I can't continue with this but trying to persevere. Been crying all afternoon. Is anyone else struggling or does anyone have any tips?
