I agree with Gray&Ella'smommy and with Em, I would go through the motions of EASY to get her accostumed to it, and she may surprise you and fall asleep. When ds was first born I use to watch him like a hawk and think he didn;t give me any sleep cues either. Until I read in Tracy's book that some babies (especially spirited ones) open their eyes real wide and get more energetic when tired. Boy!!! Did that fit more the picture!!
So I recommend you do EASY, focusing especially on the 4S wind-down and try to get her to nap more regularly and to feed regurlarly.
Remember she's still not sure where she is and what's going on, she's only 4 days old, bless her heart, and it's up to us mommies to show them when and how to sleep and eat.
Plus you need to put your feet up while she's napping!
Congratulations on your baby girl!
