I discovered about infant potty training by accident about two weeks ago. The thought of my baby's gentle skin not having to be in contact with diapers 24/7 made me think about it.
In the Wikipedia:
"Elimination communication (EC) is a process by which a caregiver uses timing, signals, cues, and intuition to address an infant's excretive needs, partially or completely avoiding the use of diapers. Diapers can be used but usually tend to become extraneous and unnecessary after a point. The emphasis of EC is placed on communication. When one practices EC, they are in essence trying to communicate as much as possible with their child about the elimination process, helping the child to become aware of their own body. The term "elimination communication" was inspired by traditional practices of diaper-less baby care in less industrialized countries and hunter-gatherer cultures.[1] EC can begin at birth and is usually started before six months of age, although it can be practiced at any age. If started in the later months or after age one, babies are more likely to be "diaper trained," and may be less aware of and/or able to communicate their elimination needs. The main components of EC are timing, signals, cueing, and intuition."
After carefuly researching the subject I gave it a try. We went bathroom (as soon as I noticed the signs) and held him over the sink. He laughed at the baby in the mirror then at me and started wondering what is going to happen. I started prompting him with "pss-pss". I just begun feeling a bit stupid and doubting my matternal insticts and a gentle stream begun flowing down the sink. He stoped for a moment seeing the baby in the mirror peeing, but continued right on. I felt incredible happiness and was reassured of my deep connection with my son.
I repeated this later after we got back from our usual walk and this time he didn't pee. Instead he went poo-poo in less than 15 sec. I discovered that this position helps also with the elimination of the gasses.
I decided to continue with my experiment by using diapers only at night and when we go out. I got him a specialy designed nappy covers for when we are at home. We do get accidents once in a while, but my confidence as a mom grows stronger and our connection with my DS gets deeper.
