Continued: everything with the long term consequences, she would do the research and change her ways. So I wrote a text stating my concerns with - the co-sleeping, pacifiers, 4 bottles of milk a day, not knowing no, running outside, hitting my dog, cartoons all day, crying when he wants something and basically getting what he wants with all the consequences. I explained that all this information with recommendations is on the web. She literally flipped a lid. How dare I tell her how to raise her kid. I am not a parent and her child is not a soldier. Again she told me he was only 2. I sounded like her doctor that questioned his nutrition because of his high BMI. He is 2 and will grow out of it like I told you. He is starting pretty school tomorrow and will start acting different then. I told her well don't send him to prevent school with a binky and 4 bottles. That really pissed her off. How could I say something like that when that's his comfort. I told her if she did her research that most babies are off by 1.5 and I didn't want him to be the only one. Also you can't understand a word he says and that is a major side effect. She went off with who am I to judge. I realized then that it was done. Because I was so mad that she was being so ignorant, I mentioned that maybe if she listened to some people especially her doctor then her son wouldn't have thunder thighs. (Only because he has really fat legs). I know this is unhealthy for the child. That pretty much ended everything. I feel like an a hole for saying what I said at the end. I just cannot understand why someone is so blind. Did I do everything that I possibly could? Did I miss something? I did not want to give up on such a great girl or be mean to her. I just saw a bad future ahead. I am really concerned about the kid and am losing sleep over it. I knew if I kept going I was going to fall into to deep. Are all mothers like tgis? Any suggestions of how I handled it and if there is anything I could do would be greatly appreciated

Thanks everyone for your comments, they have put me at ease today. I have gathered that I definitely made the right decision with leaving. I also understand that I made many mistakes during this tough situation. Yes I do know that I was wrong with insulting her child by saying thunder thighs and I am not proud of it. I regret saying it and apologized to her for saying it. It is nothing the child said or did. I was just so frustrated that such a loving mother would ignore a doctors concern and recommendation and give the doctor an excuse that he is 2 while getting an attitude that the doctor would say something about her child. If I knew more about this situation, I would have responded completely different. I did not know that there was a website like this that could have helped me. All I knew was that I saw something wrong. The something wrong I observed involved a child that I cared about, who had no control of what was going on. My first instinct when I realized this was to research and get as much information as possible so I could understand a little bit better. While I was informed of the serious long term effects of what I considered was wrong, my gut told me to try to inform and help. I saw that I had two great people that I was willing to be around for a long time. They just did things a little different. Her reaction to my concerns told me I had to take a light approach to it. So at the time I did what I thought was right. I so worried about this child's immediate safety and long term consequences that it may have fogged my judgement. All I wanted to hear is that she would be willing to listen to my concerns and work with me on some type of agreement. I did not expect everything to be done my way just some changes to help the child's safety and future. I could not understand why someone would not even consider listening. She knew how much I cared about her and her child. Every time I would bring something up, I would always mention that it is not my intention to be mean. I have always been liked by others because I know I don't know everything and I am always willing to listen even if I do not agree. I realize the importance of experience and always value people's advice. This whole thing was a complete shock to me. I was never mad at the child, I was mad because my GF would not listen to my concerns. Shutting them down always with some sort of an excuse. Every relationship I have always been able to express any concerns while always listening to my partners concerns. This was the first time that my concerns involved a child. It seems that so many people have run into my situation. Why do parents put such blinders on when it comes to their children? Why do partners not understand that it is also difficult for someone coming in and trying to be a parent? It seems to be all about them with no consideration of their partner. This was one of the hardest things I had to do. Just thinking of ways to say something and how my stress it gave me. Nevermind the stress of leaving.
