You are lucky to have such a good caregiver and fun playmate for your lo.
My dd cries in the morning when I drop her off at dc and leaps into my arms (and stays there) as soon as she gets home. She even cries when dh tries to cuddle her! Sometimes I wish she were a little more independent . But I realize these are all phases. Someone told me separation anxiety peaks at 18 months (next month!). Gosh I hope so!
Next week your daughter will probably be velcro baby and mine will be running away from me. It is interesting to watch them going through these little cycles of push and pull.
