wow what a response! thanks for your thoughts everyone. i think i'm definitely one of those overdressing their babies to sleep. ethan is going to sleep in a singlet, a long sleeve bonds thermal (without legs), a romper, a snugtime sleeping bag (i'm not sure what weight it is but it's pretty thick) and then a blanket over the top.

it gets really cold during the night so i just thought it best to keep him from getting the chills i sometimes feel at night. i'll probably go without the blanket from now on and see if he wakes during the night.
