Separation Anxiety?

Now that Josiah is 6 and a half months there have been some things coming into action.
First, off Josiah has been a sleeping through the night baby 95 percent of the time since
he was 12 weeks old. We also had our nightly routine of getting him dressed for bed, nursed, and read a book then put him to bed awake and he would put himself to sleep. Since turning 6 months he has started waking up in the middle of the night just wanting to be held and rocked and we can no longer put him to bed awake without him screaming. I was looking over our paper that we got from our pediatrician the other day while I was wondering what the heck is going on with my well behaved baby. The paper said that at this age babies tend to have separation anxiety kick in. Ahhhh, now it makes sense! So for now we have resorted to rocking Josiah to sleep at night and cuddling him and rocking if he happens to wake up in the middle of the night too, which thankfully he has been waking around 5:30 for that which is not aweful I suppose.... I guess for now we will just wait it out and pray that this phase will go away soon. I never want my baby to feel insecure or worried that mommy or daddy will not be there for him when he needs us. In other news, Josiah continues to be a joy to all. I really thought that people just stop and stare at babies when they are newborns because they are small and cute and well, who doesn't love a nice new baby? However, whenever we are out Josiah continues to atract attention wherever we are. He is starting to raise his hands when he wants to be picked up, is eating more and more solid foods and my new favorite thing he does is says " rooooooooooooooooaaaaaaaaaaaaaaar" when asked " what does the bear say?" He is such a joy and I am constantly learning so much from him about life. I just want him to stay my sweet, innocent, little boy for forever :)
