Daily Decrease

My son is 11 weeks old and he’s taking almost 6 oz bottles. Whenever I breastfeed the whole day, he’s satisfied and takes 2 naps that are about 2-3 hours long. When I’m at work, my family members watch him. He eats, plays, and barely naps. Sometimes doesn’t even make it to the next feeding time before he wants more milk. I pump at work and I only get 11 oz/day right now but my supply is increasing 1/2-1oz a day. The first pumping session is always a full feeding for him. I have to pump 20-30 mins to get that. The other two sessions are only 2-3 oz max. 😓 There is no milk stored at home because I didn’t pump on my maternity leave. I didn’t because my supply was initially messed up by 4 different lactation specialists telling me different things. I have not seen them again and my supply has regulated. However, this means that my son only gets what I pump the day before and then is supplemented with formula. 😭 He is fed, yes, but when I get home, it’s like I can’t produce enough to satisfy him at night. I’m taking fenugreek and eating lactation cookies with brewers yeast, flax seed meal, and wheat germ in them. I’m drinking four bottles of water a day.

Sorry for the long explanation, but can anyone help me and my son?
