Thanks a lot for all your advice!

I took my baby out for a walk (well,difficult to call it a walk,cause she was in my arms all the time) to the park and we stayed under the sun on the grass what she enjoyed in particular. So, i tried to pour some water in the tap of the bottle and she drank several with pleasure. I guess she's like all those babies who enjoy being fed like that
And here is a pic of Bunny walking in the park! Oh,I Love HER
