DD is almost 14 weeks. We had a difficult start to feeding - poor weight gain, bad latch, thrush, pain and hideously cracked nipples - but she was finally diagnosed durn posterior TT at 11 weeks. Progress has been steady - weight gain is improving and I'm not in pain. She's gradually becoming a better feeder (she's EBF on demand) but as she takes more milk she's increasingly showing signs of reflux/silent reflux. She's sometimes screams at the boob but I can't always get wind up, sometimes will refuse feeds altogether though appears hungry, sick is always curdy and when she's not sick can sort of hear her swallowing it back down, goes from happy and chilled to total meltdown in an instant and appears in pain, often cries incessantly, and is increasingly unsettled overnight. Getting her to sleep in the day is an absolute nightmare, too - I watch for cues like a hawk and try not to let her go more than 90 minutes without a nap but still I'm lucky if she will do 60-90 mins during the day in total. I spend far far more time rocking, shush/patting, whatever than she does sleeping. She maybe will do about ten hours total overnight, usually broken by three feeds. So she's clearly overtired but whatever I do doesn't work. Buggy/car/sling work occasionally but aren't guaranteed. I just don't know what to do. I feel like I'm failing her. Anyone tell me where I'm going wrong? I'm at the end if my tether.
