Most babies who are ECed are out of daytime diapers by 9-14 months. Some rely upon diapers only for pees.
Definition of Elimination CommunicationEdit
Elimination Communication, also called Infant Potty Training, is a gentle, non-coercive way to respond to a baby’s natural pottying needs, from as early as birth, which honors her instincts to not soil herself, her caretaker, or her sleep space. 
Practicing Elimination Communication is beneficial to baby, parents, and the environment alike. Here are the main reasons why it is a great diaper alternative:
- Use less diapers
- Save hundreds, if not thousands, of dollars
- Less diaper waste (4 billion diapers a year)
- Deepen connection between baby and parents
- Easier potty independence
- Save time
Timeframes and ExpectationsEdit
Doing EC with your child does not guarantee potty independence any earlier than another child, but on average, kids who practice Infant Potty Training, are out of diapers anytime between 12 and 22 months.
Completion is part of every process so you can very well expect to complete at some point, and I totally empower you to guide (not force) your child towards that mastery that every toddler deeply deserves.
Next, I want you to know that, depending on where you learn EC (did you wing it off of Facebook advice or did you get a professional’s trusted guidance), when you start, and the unique temperament and development of your baby, it’s reasonable to expect a certain level of daytime dryness by 6-20 months.
Observing during ECEdit
The first step to successful Elimination Communication is observation. During this time, you will learn your baby's cue's and signals that he/she needs to go potty.
You’re going to look for some things in particular:
- what happens right before she pees or poos?
- how often after feeding does she pee or poo?
- how often after waking does she pee or poo?
- did you “know” or have any intuitive thoughts when she was about to go?
You’re also going to start doing sound association: every time your baby pees, cue along with her with the “ssss” noise. Every time your baby poops, cue along with her with a grunting noise, “mm, mm,” or another noise or word of your choosing.
This noise will later become the cue you give to your baby once she’s in position and it’s okay to go ahead and pee/poo.
