B.H.
I don't think it's a huge deal although I know from experiance it's much easier to take away all the security objects, blankie, pacifiers, bottles, animal before age 1. After age 1 it get's harder and they get that more attached.
I couldn't take away my daughter's things before one, I had a huge guilt trip and felt bad but now if I have more children I probaly would work on taking things away before 1.
A trick I've heard for the pacifier is cut off the nipple and just give them the plastic piece and they loose interest in it.
