I had the ocean wonders mobile with the remot and it was awesoe i loved it

My suggestion is to just let her cry it out! You cant always nurse her to sleep..I mean you can but if you dont want to anymore then absolutely you have to break that habit. I always nurse my son and then wake him up a bit and let him just hang out until it is 7pm when he is supposed to sleep. He usually falls asleep at the breast at 630 but I wake him up by putting him on his play mat and then at 7pm put him in his bed for the night with nothing but him and his blankets he goes to sleep straight away. I did the CIO method early and he is just a good sleeper to begin with. I hope this helps you.
