Our 7 week old just doesn't seem right. GP, HV All say everything is fine, weight gain etc. Have done so much reading and it looks like reflux as well as colic. Went to A&E yesterday and they did blood test with result of low sodium and iron, concerns of borderline dehydration. We're then given anti reflux milk (the thick stuff) and told not to worry about mild possetting or vomiting and only worry if it is projectile. 2 feeds into the new milk and we had the first ever projectile, and another later. She has now settled and 12 hours with only minimum possetting as we Have reduced the amount and increased regularity of feeds but now she just seems lethargic..with intermittent sudden bouts of really painful crying. Other symptoms like legs going crazy, arching of back during and after feeds...my wife is trying so hard, I don't know how to help either of them. Are we just nuts, are we really doing something wrong or are the health professionals missing something...any advice is really really appreciated. I'm sorry I'm a dad posting on here but I don't know what else to do. Please help.
