@potluck45 You do you. I have 2 kids and the best advice I can offer on child bearing is if you are positive you are doing what is best your family then that is what you are going to do. Notice how i say best for your family - this includes both parents and kids.
Now about specifically baby sleeping and sleep patterns: the phases change. Constantly. So no point in putting a lot of effort in "teaching" a baby how he should fall asleep, when to sleep and where. Babies have sucky days too and most of them handle it badly hehe
Remember people are trying to be helpful (most of the time
). So when they offer advice whatever it is, say thanks I'll try that tomorrow, he is in a really bad mood today. He is probably teething/had a horrible night/whatever so I'll keep him on me today.
Don't let others' words push you into actions you do not approve. They are just words. You choose to accept or (politely) disregard.
And to wrap a long post: its tough being a first time parent. You're scared and are constantly questioning yourself. Chin up, enjoy the cute parts and it'll get better.
Take care xx
