Hi S.,
My daughter was that way for about 3 months. She then settled down. Try this.
Take a nice fleece blanket and put it on the bouncer. When she falls asleep, wait for 20 mins. Thats prbly how much time it takes for her to enter deep sleep mode. Then, carefully place her in the bouncer. She will wake up once/twice...then she will stop waking up. The blanket is the trick. It makes her feel that she's with some one.
Same applies for the crib.
Swing - well, my 4mo old still doesnt like it. But the times that have worked are because after she is deep asleep, I start the swing and let it moving. Then I carefully place her in it. I think she thinks that someone is holding her and walking. Remember to keep a blanket in the swing too.
It will work with few tries.
