after that 10 days, baby was obviously closer to me, but she still prefers to let helper to put her to sleep. as i spend more time playing w/ her, she shows more affection towards me. but the down side is- even as i turned my back, she'd start screaming. so i had to tell her i was just going potty (etc) and will be back very soon (& i always keep my promise). i am a stay home mom & it obviously helps. as for my husband, he has to work, and the more time he spends w/ her before & after work, the closer she is to him. for several days he was late coming back & didn't spend much time playing w/ her, in the morning, she wouldn't hug him.
so what i'm trying to say is, i had the same problem when baby was small, and i was upset & worried & depressed. as she grows older, she show obvious signs that she knows i'm mom. she has a bond w/ me that is different than w/ nanny, although she shows much affection towards her too. if u spend quality time w/ her, one on one time during the weekends, before/ after work, i'm sure you baby''ll be close to u too. it's just that she doesn't want u to put her to sleep. but think of it this way, u'd be able to able to go out when you NEED to & not worry that u have to spend hours putting her to sleep. i still make sure that i'm home EVERYDAY during her nightime routine - bath, milk, & a little bedtime mellow play. but i'd be able to leave when she's ready to sleep & not worry that I'll be so late for my dinners. I know a lot of moms who has your problem, but they all told me that in the end, baby knows who mom is.
and remember, you are her mom for life, nanny is only gonna be there for severals years. you have a love for her that no one else has (maybe except dad, but i think moms love their children differently than dads. sorry, dads!) and she can feel it.:bighug
