Hi I'd prob start with trying to work towards 1 nap so for us with DS1 we did
WU 6am Nap 11-12.30 or longer then CN 30/40 mins around 3.30 pm BT 7/7.30pm
DS2 WU 6.30 CN 9.30am for 30/40 mins then long nap 1pm-2.30/3pm BT 7.15/7.30pm
If she is more tired but not OT you should get less resistance at nap/BT. I'd stop the feeding to sleep and make sure the feed is done and followed by teeth clean, story etc then lots of cuddles and into bed.
With GW you would put in cot, sit near him but just reassure very quietly so just a sleep phrase and some shushing maybe, if she gets upset quick stroke, pat or cuddle but back down and repeat repeat really.
It will take a few days as you will gradually move a little every 2-3 days away until you get to the door etc.
