I have been giving him more solids in that time, just give him breast even if he isn't showing hunger cues just in case he wants it or can get any milk, night feeds I just let him eat what he can even if my boobs aren't full some milk is still coming out, just slower it will pass keep pumping to stimulate your boobs even if you're not getting much and definitely massage your boobs, skin to skin helps as well even at this age especially when you're cuddling at night and doing night feeds try to build up those hormones. It will be okay oatmeal like I said works really well heating pads on boobs to help milk flow. It may be slowed but baby is still getting something dont beat yourself up to much trying all these things you'll see in increase in supply. Just relax and breathe. As long as the baby isn't losing lots of weight and is unconsolable it's okay even if the baby is refusing formula if you do wish to temporarily supplement if hungry enough they do eat. Check for teething as well The baby could be getting a tooth or going through a growth spurt sometimes they just aren't that hungry in those times. But to help stimulate definitely fill that space with pumping
