so many styles

There are so many parenting styles out there! Attachment Parenting is one I first saw verbalized today... Parts of it I agree with and seem like common sense instinct to me, other parts seem a bit extreme. It's odd to me that parents who hold to this line of parenting also tend to be a "no negative reinforcement" bunch. Spanking is like a cuss word among this group. There is such a fine line it would seem between being sensitive to your baby's needs and letting your baby's desires run your life. Speaking as a mom with a strong willed baby, if I never let Olive "cry it out" or never gave her a negative response, she'd be up most of the day most days, and a screeching squealing little girl. I look into the eyes of my beautiful 5 month old and can see that already she's looking for approval or disapproval. She's searching for boundaries, curious about what we think. True, more often than not she can't quite figure out why we don't immediately trade to her team the moment she flashes a smile, but I know that already she's learned who to take her cues from... I agree with the bonding, attentive, sensitive nature of attachment parenting, but also acknowledge that we are born with a sin nature (see Psalm 51:5) which needs to be curbed.
The issue of the month for me is sleeping through the night. Since Olive and I share a room, I am there any time she fusses. She's established a schedule when she wakes to feed around 2AM and then wakes around 6AM to be transfered to my bed. Why does she need to move to my bed to continue sleeping? I don't know! I don't understand it at all. It was sort of sweet at first, like she missed me or just wanted to be close to me. Now I'm getting weary of catching 4 hrs of sleep at a time and waking up sleepy. I guess I'll just have to trust that God will grant me the patience and fortitude to last longer than this phase : )
