I had the SAME PROBLEMS! So very confusing. I'll let MedHelp know how confusing it is.
I figured it out. I deleted the page and started all over again.
It is so weird, I changed Evan's to say this page is for Evan and filled in all his info, then I looked at Noah's and all of his info changed even though it originally said this page is for Noah.
Are you looking at the Page Settings? The little gears button in the upper right? If you click on that, and then click Settings, it should say that the page is for Evan, not Myself or Noah. If it doesn't, try changing it to Noah.
Then if the About Baby still says Noah, you can remove the About Baby and add a new About Baby and say it's for Evan. See if that works.
I checked the box that says for someone else and filled in the name, it still changes Noah's info and turns it into Evan's. This is so frustrating.
It should ask you if it's for someone else say yes and it should allow you to input the new info. I will try it out and see if I can get it to work.....
