Re: Lots of issues...in need of advice.
Ugh, I'm with you on the gas, horrible smelling gas, painful gas, etc. My husband's family swears its genetic to their family... I dreaded mornings the first 4 months (son is 6 months now) because the gas was constant, putrid, and lingered. I spent hours in the stink cloud. Yuck. I have low supply and supplemented with formula too until I found a kind donor mom. Since my son has had 100% bm and I changed how I positioned him at feedings (initially for reflux issues but it really helped with gas) his gas has backed off a lot. I sat reclined with his legs straddling one of my legs and fed him on the opposite breast. This is a great position and no boppy is needed. He still is a very flatulent baby, but its not as painful apparently as it used to be. At night too, if he has a gas attack,I just lay on my back lay him stomach down on my tummy and (rather hard) punch his bottom...this alwatlys makes him release the gas instantly though I think its rather rough. I think the pressure on his bottom and the pressure on his tummy work together well. Anyway, I never changed my diet because I was needing to take galactagogues for low supply and they caused gas on their own... hope this can help with your baby's gas problems.
Also, sounds like your baby has reverse cycled on you ...becoming a night feeder and holding out during the day to eat. That works for a lit of moms who work days...its nor too unusual. If she is thriving otherwise I wouldn't stress too much since its only 3 times a week. Also she likely preferred formula when you're gone because its more filling. She doesn't want to eat without you but if she has to, I'm sure she'd prefer to have something that will keep her full longer. I think how your husband is handling it is working. When I supplemented. With formula, my son wanted to go 4 hours without breastfeeding. If you want your baby to consume more milk to make up for her long durations without it, try supplementing your feedings with an sns at the breast, once she drains you undo the clamp and keep filling her up.
Hang in there too, you have a lot you are already doing and dealing with. Keep it up, breastfeeding constantly changes day by day week to week and monthly. You may get through this episode fast. I'm totally amazed how much baletter things have gotten at 6 months for us.
