That sounds like a good plan. Just in case it helps, this is the routine my DS was on at 7 months:
WU: 6:30/7
S: 9:30-11
S: 1:30-3/3:30
BT: 7
It worked quite well for a few months. I did set naps (same time each day) rather than A times because I got way too stressed with chasing A times with DD and it worked great. Even if he slept later, he was still ready for a nap at 9:30 and even at 10 months still likes the same nap time. I think something similar would work even with a 6 am WU as the book it's from says a WU anywhere between 6 and 7. We dropped the 3rd nap sooner (at 5 months) but we dropped it quite quickly and then I just aimed to put him to bed 3 hours after his last nap ended.
Was the paci becoming a prop? Do you think losing it will help with NWs?
