QUOTE A question - all the young potty trained babies, can they pull their own pants up and down (especially boys with pants and trousers) and can they hold their wee for any length of time?
ECing is NOT toilet training, it is a way to give babies/toddlers the choice of eliminating outside their pants/nappy into a potty/toilet.
Babies have limited control over their elimination from birth. I can only comment about babies from 10 weeks old (as that is when we started) but DD quickly learnt to wait to use the potty. When she was little she could only hold on maybe 15/20 minutes between wees and maybe 40 minutes by 11 months. But once we eliminated dairy from our diets, she started to have 4 hour gaps between wees and had very strong control.
At a year old my ECed daughter would sign 'Toilet' to me, I would follow her upstairs and lift her onto the toilet and pull her pants down. She would wee, take toilet paper off me and wipe herself and lean back and pull the lever to flush the toilet. I would pull her pants up again and lift her off the toilet and take her downstairs. So she clearly shows her preference whilst being unable to dress herself. In fact she is now 15 months old and sometimes try to pull her pants up but it will be months/years until she can dress.
But dressing is nothing to do with using a toilet. Just like we spoon feed children, who can't handle spoons yet and we bottle/breastfeed babies who can't handle a cup yet.
ECing is just another choice of how to handle eliminations BEFORE toilet training. You can use nappies 100%, ECing 100% or a mixture of the two.
