My midwife warned me that it’ll be pretty dry for a while, especially if you’re breastfeeding. So even if you rarely or never used lube before, you should use some now! For postpartum, I recommend a water-based lubricant made for sensitive skin
My first born is 3 next month and I never got as wet as I did before, we always had to use lube
How long since you gave birth? It took me 7/8 cycles to fully feel as wet as before but I was tracking cycles we tried for baby number 2 very quickly.
