My baby falls asleep when being carried and wakes up when put down.
Carrying is extremely relaxing for babies and simulates time in the womb, especially through movement. When the baby is put down, the movement stops and the baby wakes up - this is quite normal. Practice putting the baby down without pressure from time to time - experience shows that it works best if you first put the bum down and then the baby over the side. The kangaroo carry is very suitable for putting the baby down - try it out!
