Pumping schedule 3 to 4 times

I’m almost 10 weeks PP and the whole 3 hour during the day is too much. I go 4-5 hour stretches at night fine (schedule looks like 2am, 6am, 930am, 1230, 330, 630, 930). I get more than enough milk and I can’t even freeze it since my LO hates the lipase in my frozen milk.

How can I get to 4 hours during the day? I’ll honestly be fine with the MOTN pump for a little longer if I can get longer stretches during the day. 2, 6, 10, 2, 6, 10 sounds much more do able.

Should I just cold turkey? Once I do this, when can I drop MOTN pump? Anyone w experience going from 3-4 hours is helpful!!
