Should i start getting her to give them up?

My daughter is eighteen months and still uses a pacifier and a bear-bear (comforter blanket) as security, i dont let her have her bear-bear outside the house unless she stays somewhere but i do let her have her dummy in the car and at night when she is tired (and as a last resort when we are out and she throws a tantrum). I am constantly being told "she doesnt need that, she won't talk" (mind you her speech is more than fine). I dont mind either of them as a comfort for sleep, but i am starting to get concerned how often she will come out of her room having found a hidden (she hides them) dummy and pulled bear-bear through her cot rails.....Like right now its 5:12pm and she has been at daycare today and half an hour after coming home she is sitting quietly watching tv with bear-bear and her dummy.....what do i do? I feel awful taking something she loves so much away??!?!
