this is normal and healthy for her age. even through a year old or longer this is normal and healthy. babies need to wake often for survival. this keeps them from getting into too deep a sleep, and it also keeps them filling their tummies; think of it this way:
your baby's tummy is about the size of her fist. thats really small!! in the first year, she will triple her weight and double her height. this means she has to eat often!!
no one says being a parent should be easy, and parenting doesnt stop from 8pm - 8 am. you have to parent around the clock. crying is her only form of communication and i urge you to follow your instincts when she cries. if that means you go to her, then go to her. if that means you let her lie next to you to sleep, then do that. it isnt a "habit" it is a beautiful survival skill. babies who lie next to their parents regulate their breathing and heart rate to their parents. this is very good and very healthy for babies. she also knows then, that you are there, that you will respond to her, and that she doesnt have to be alone. this actually promotes GOOD sleep habits. but you have to know your child. to do that, you have to keep responding to her cries in the way your instincts tell you to. dont listen to other people, dont listen to doctors, dont listen to books. listen to yourself. you are the only one who knows your daughter as completely as you do, and you are the only one who has to deal with the effects of any parenting choice you make. this is important; you have to listen to your baby and listen to yourself. when shes ready to be left alone for a time, you will know, but you have to listen now to get to that point.
anyway, i hope this helps. i want you to know that there are studies out there that show that moms who sleep near or with their babies get much more sleep than moms who dont... so you are doing the right thing! especially if you feel its what you have to do. just keep following your heart!
babies this age might still have trouble holding the nuk in their mouths or retreiving it for themselves when they lost it. so feel free to keep trying to use it if you like.
anyway, the end result is this is normal, this is healthy, and what you are doing is not wrong. what you are doing is following your instincts and doing whats right for your family. dont EVER let anyone tell you that you are doing anything wrong, that you are causing bad habits (theres no such thing with babies!!) and that you are spoiling (again - no such thing with babies under 1 year!!)
so keep up the good work. :) trust yourself!
