Pumping - help

Photo so we don’t get lost!! I am 6 weeks pp, and I have not pumped unless my LO is getting a bottle from my husband before bed for bonding. My LC recommended I start pumping the opposite breast after baby feeds because he only nurses on one side per feed. Or else she is afraid I might lose my supply when the 12 week regulation occurs due to “infrequent emptying” as sometimes each breast is going ~4-6 hours without being fed from. I do however use a boon trove on opposite side and catch ~ 1 ounce each feed. Right now my LO is eating every 1.5-3 hours during the day and every 4 hours at night. If he nurses and I pump, when I go to feed him next, how do I keep him content? I won’t have as much right there and readily available, and he doesn’t like to work for the milk. My question is: When first starting to incorporate pumping into your EBF routine, how do you deal with the “lower supply” (due to increased removal) when actually feeding? I know in a few days my body should start responding and making more, but those first few days seem so daunting.
