Sorry I have forgotten how old your LO is... we are in 2-1 at the moment and (this week!) seem to be having success with capped morning nap, longer pm nap. It's basically 3hr A, 30 min nap, 3 hr A, 1.5-2hr nap, 4hr A, BT. For us that means naps at 10am and 1:30pm but with a bit of room to jiggle for swimming, school run when she's with my sister, etc. We were getting pm nap refusal and this seems the only way to keep 2 naps for now.
