From my experience one can't escape it, one just accepts it. I think some parents will always see their children as children or babies, nothing is wrong with it per se. It's just the way it is.
In the overall scheme of things, you ARE still a baby.......
It could just mean that she loves you very much. And that she doesn't want you to grow up too fast because she is going to miss you. This is because when kids get older they become more distant from their parents. So just show her that you love her a lot and she will probably stop. :)
There's not really much you can do if its because ur mom is over protective but if its because you act immature or something that could be it
Quite acting like a baby.
stop ******* your mother get help seek professional help
Do you behave in a responsible manner? If not, that could be it.
