So very normal. It will pass, and it will get easier I promise. She is just learning that mommy can walk away and that you arent attached lol. She is becoming very aware of her suroundings and sounds like the seperation anxiety is setting in.
Is she breast fed baby? If so she probably just doesnt want to be to far from the snack bar lol.
Not to young to cry for a moment or two, just talk to her while your not in her sight, tell her mommy will be right back, and then re-appear as soon as possible. Show her you will be back.
Because infants minds are still developing they dont know that mommy will be back, all they know is that mommy is gone. It will take time for her to learn. And nothing wrong with giving her a little love when you do come back to the room to her, to show her everything is alright.
Try not to fret, it will be okay, just be patient, and before you know it she wont be doing it anymore, and will be self content.
Best wishes!
