AMH
Sounds like you're having a pretty rough week! Any friends you can call on for a bit of help?
She's still gaining weight - that's good. Remember you need to average the gains over a 4-5 week period to get a true picture. The gains can vary enormously from week to week. How is she otherwise? You mentioned reflux? How is that going?
Try to make things as easy on yourself as you can to get through the tough times
