When your baby is sleeping through the night but you wake up engorged and in pain that you have to pump for relief....I ended up pumping 2- 4 oz bottles and a little extra.
@sev1226 thanks for commenting. I'm glad you mentioned this because sometimes I'm tempted to just sleep through it so this was a great reminder for me.
My biggest regret is not keeping up with pumping once my lo started sleeping through the night... I didn't realize missing those night feedings would cause my milk to re-regulate and decrease. It's been a challenge to get it back and I still don't think I produce like I did.
