Hi A.:
You know, your daughter was accustomed to you rocking her prior to each nap. The reason she was so willing to sleep without your rocking her,is because you had built a bond,a closeness,that provided security for her, Secure enough to make her feel safe just laying down by herself.However, she is beginning to (Miss) you rocking her. (She ALMOST forgot what she loved about those naps but shes sharp enough to remember now. What I would do A.,is rock her again a few times and See if that makes a difference. It doesn't have to be everyday,but periodically,so she doesn't feel shes missing that special time with you.If that doesn't do it,then i'd try to change up her naps,or limit it to one. I know us mothers need every break we can get during the day,but don't make it a struggle,or force it to the point she hates going to sleep.If shes tired,she'll conk out.If shes not,let her lay and talk to her lovey for a while and get up and try latter.I wish you and your darlin daughter the best.
