Finding time to pump with newborn & solo leave

Hi all, I (35/F) need advice on how y'all are sticking to a pumping schedule with newborns/demanding babies. My husband and I are staggering our parental leave so I am home alone with our son (3 weeks old) for the next 4 months. I am exclusively pumping for now as we navigate latch issues.

How do y'all commit to a pumping schedule with a crying newborn? I keep finding myself being 1-2+ hours off my pump schedule because baby starts crying and I need to feed, change, burp, walk him around...

I use a spectra S1 with a MomCozy bra but no wearables. I'm trying to build up my supply as well, currently produce ~4oz pp.
