The bink and I have a love/hate relationship

DD has just started to really like the bink again.  She loved it when she was really little but then stopped wanting it.  Now, the love of the bink is back.  She does not get it at all during the day at daycare or my MILs.  At home on the weekend she sometime will nap with it but not all the time.  She usually goes to sleep at night without it (not this week but that is a story for another time) but wakes in the middle of the night (or if we are lucky early morning) and won't go back to sleep without it.  It is so strange.  I wonder if it makes her gums feel better (I don't see any teeth but she is chomping on everything!)?  I love that it makes her fall back to sleep but I hate that she needs it and getting up 5 times in 30 minutes to put it back in before she falls back to sleep again!
