I need help!!

Elizabeth • BFP on 4/10/17 for baby #2 ❤️ [Baby #1 = Jan 2016]
My baby is just over 2 weeks. I'm exclusively pumping due to having an over supply and bc I had some medical issues when I came home from the hospital (my husband could help by alternating feedings w me). For the last 3 days she has had such bad gas that it's seriously impacting her sleep. I could cry.
She will eat and be up for 2-2.5 hours just bc the gas. I've tried: long sessions of burping, a different colic bottle, wearing her, a pacifier (I'm desperate!), and Little Remedies gas drops. PLEASE HELP. My anxiety is peaking now that it's night time. I feel so bad for her.
