My daughter crawled to her room, climbed inside her bouncer and started to fall asleep. I have the heater on in her room so it's all nice and warm. But as soon as I walked in with a bottle she got upset that I took her out of the bouncer so she's in the living room laying in her bouncer with a bottle and blanket. I don't know why but she hasn't used her bouncer since she was about five months and now she's back to loving it.
