Thanks ladies for the great advice!
I haven't been able to try them yet. The night b4, dd had 2 NW, 9:40 (40 min after BT) and 3:45. I just lay her down at the 1st one and she settled but the 2nd one was horrible, she was up till 7! She wanted to sleep though, but stuffy nose and DH ( who wanted to read her a book at 5 ) kept her up.
I didn't had the heart and energy to start her day at 7am so I let her sleep and she woke herself at 10am. fell asleep in the baby bjorn at 1pm for 40 mins and I AP a catnap of 30 min at 4pm.
last nite went ok ish, one NW at 12:45 and I settled her by holding her hand for 15 min. woke at 6:30am this morning, looking refreshed. Resisted her 1st nap until 11ish when she doze off in car seat for 20 min, had her kiddy gym then wanted to doze off again in car seat at 2ish but I kept her up till we reach home. She didn't want to sleep when we reach home ( mayb OT already?) so AP nap again at 3:30pm and she woke herself crying at 4:50pm.
I don't know how tonite will be, BT was relatively easy at 8:30pm but with a nap so late...
the 3.5ish/30/4/1.5/4.5 schedule sounds good, I'll try that
