Hindi naman masama, mama! A few of us do the same thing, if sterilized na, okay lang gamitin agad kahit konti pang ang moisture, especially pag rush ka sa feeding time. The sterilization kills the germs anyway, so that's what matters most talaga. Just make sure talaga na properly sterilized siya (either through boiling, steamer, or UV) para safe, at kung makikita mo may dirt or residue, then wash and sterilize ulit lang.
