Milk supply

Lauren

Help! I’ve been mixed feeding my bub since week one as I haven’t had a large milk supply and it just doesn’t fill him up. I’m in week 3 now and normally I’ll breastfeed him in the morning and express twice a day where possible to give him whatever I can. We were out all day yesterday and didn’t have a chance to express so I expected to wake up this morning sore and full but I struggled to get 20ml out! Normally I can at least get 110ml between both which is enough for one feed. Could my supply have dwindled that much in just 24 hours?
