bottles and attachment

So my judgment is still pending about my latest idea with our little foster girl. I bought baby bottles. I have read in multiple places and been encouraged by multiple people to try bottle feeding with little girl. We know she has been neglected and was not well cared for as a baby. She acts like a baby often and wants us treat her like one more often than we would like. The experts are telling us that is encouraging because she is trying to form attachment to us. I am not convinced but they do know more than I do about this. So I have tried a bottle twice with different feelings about it. I think it is good for her and will keep trying but not sure for how long. One bottle a day is good for her to be held and good for eye contact and good for her to get the nutrition of milk in her body. She does not drink very much and could use some more hydrating so the bottle feeding is helping with that too. She is not the biggest fan of milk so I wonder if that is because she wasn't given that much of it...who knows.

We continue to work on attachment with her, which really just means being very intentional about loving her and meeting her needs. On top of that there are lots of discipline issues remaining. Multiple daily tantrums/outbursts/emotional breakdowns or whatever you want to call them still remain a part of our life. On top of that we are still dealing with the negative behaviors that have developed in our boys after she arrived.

The last 3 weeks have been rougher than the previous month because birth mom entered the picture again. This made little girl have more fear and more bad behavior because of that fear. She doesn't know what is going on. Who will she live with and what is in the future? We reassure her with our best ideas and explanations but we know she can't understand all of what we are saying to her. Her mom is trying again and states that she is off cocaine and only using marijuana. She is seeming more normal and talking and interactive but we will see how long that lasts. She is still living with her boyfriend who uses and sells cocaine and there is physical abuse between them. Very bad environment for little girl. I can almost say with certainty that she will not be returning to her mom. Mom has only 3 more weeks to prove herself and move out or get into treatment or the process to remove parental rights will be started. The parental rights will most likely be terminated in April or May and little girl will be available for adoption.
