Boleh je increase sikit-sikit, tapi better check dengan doctor dulu sebab setiap bayi berbeza, ada yang minum slower, ada yang demand feeding. At 1 month 6 days, usually around 2-3 oz per feed is normal, so you can try 2.5 oz or 3 oz and tengok macam mana baby respond, tapi if you're worried baby tak dapat enough, pediatrician boleh guide you properly. You're doing great, mama, trust your instincts juga!
