have you tried giving your lo tempra/tylenol before bed? that's how i differenciated between the two. my dd sometimes will cry as i walk away too, and i find if i just stand over the crib (no eye contact, etc ) and keep my hand on her belly or chest (depending on how she is laying) for a min or two she will go to sleep no problem. as for the seperation anx. have you tried a lovely with your smell on it? works wonders over here!
