Helping breastfed baby poop?

Nabi • Mom of 2: girl born in 2015 and boy in 2019

My son is 13 weeks old and exclusively breastfed. He usually poops every day, usually more than once and often huge amounts. 🙈 So while I know that some babies can go for days without pooping, that’s just not him. Except now he hasn’t pooped in 2 days and he is very obviously uncomfortable. I have tried tummy time, massaging his belly, bicycle legs and probiotic drops.

Do you have any recommendations of what else might help him? I have read about giving them a spoon full of oil, but is that safe when they are still exclusively breastfed?
