Drowsy but awake Mommas

I am wanting to begin lying my daughter down drowsy but awake for naps, and eventually to bed when she gets older/used to it.  She has already done this several times and with a lot of success putting herself to sleep.  My question is, how long does it take your LO to fall asleep?  Sometimes, DD is lying there for 15-20 minutes or so.  Then she will start fussing.  I know this is because she is tired, she is showing all her signs of tired.  Her pacifier works well, but only for a while.  Is this a normal amount of time for her to fall asleep?  I'm a FTM, so I am clueless.  Any ideas on how to help her fall asleep alone?  I am not sure if she is too young to begin this or not...  TIA!
