Pumping/work supply vs. on-demand on weekends

I am just curious how my not so lovely work schedule might impact my ability to nurse on the weekends.  I pump one side at 5:30am, nurse DD on the other side at 6am, pump at work at 7:30am and 12:30pm, then nurse DD again at 3:30pm and whenever she wants for the rest of the evening.  Normall about 3 times (3:30, 6, and 7) then I pump at 9pm and she generally wakes once at 3am.

 I am wondering how my limited daytime pumping may eventually effect my ability to feed her on demand on the weekends.  She gets between 3 and 4 bottles while I am gone (8, 10, 12 and 2; 3oz each, but lately she's been skipping the 2pm bottle because she is napping longer).

Thoughts?  As much as I'd love to pump to match her feeding schedule I am unable to take a break at work between 7:30 and 12:30.
