Wow I was replying to the post about the baby drinking out of a cup and it went poof? Guess some jealous moms with their 3 year olds still drinking a bottle and in diapers can't handle a good mom that actually works with her kids instead of being lazy. My kids were all breastfed and I introduced a cup, not a sippy, at around 6 months. I started potty training at around 5-6 months when they could sit up well on their own and they were all 4 completely potty trained by a year old. My oldest could not walk yet and would crawl to the potty. Some moms need to quit being lazy about teaching their kids things and using the excuse the kid is not ready. Unless they have a developmental issue they are ready, the moms just are not ready to actually take the time to do it.
