Pump and store the milk
Give them a couple of days, feed on demand and just maybe squueze abit out when feeling engorged. The more you pump the more you will produce. Just keep latching baby on. Good breastpads i always swear by lasinoh ones x
It gets better and settles, I still vividly remember my milk coming in with my first, felt like someone had filled them with concrete, it does ease though!
Mine felt like they were on fire and hub found some gel packs in the freezer from football injuries so i popped them in my bra. Never felt such relief
Can you just a manual pump to express some more milk off?
