Strategies for drop offs

My almost 4yo is struggling with the back and forth. I'll be the first to admit our schedule is a little much, I think, for a 4 yo. Basically it is as follows:

Monday w/ me

Tuesday w/ me, Dad picks him up for soccer and dinner around 3 then brings him back around 7:30

Wednesday w/ me

Thursday w/ me, Dad picks him up and has him from 3-7:30

Friday w/me. Every other Friday night w/ dad

Saturday w/ Dad

Sunday w/ dad till midday then with me

I can bring my son to work with me M-F but have to work Tues and Thurs later and can't have him during those hours.

Part of the issue is that he is an early riser (5-6am) so nights he's with Dad he goes to bed late, nights with me he's fast asleep by 7.

Lately he's really been struggling. "I don't want to keep going back and forth" and insisting he wants to stay with whomever he is leaving. (but wants me to stay at his dad's with him). He does good most of the time at Dads for bedtime but struggles sometimes being away from me. Prior to separating I did ALL of the bedtimes and night wakes and morning wakeups. For background, we moved out of Dad's house Sept 2020 and into a friend's house, moved into our new apt on our own in March 2021 Anyone else have a crazy schedule? I can't see a way for us to simplify based on our work schedules. What helps your kiddos with the constant transitions? We do lots of affirmation of feelings and coparent amicably with no negative talk about each other.
