I have difficulty putting my 2 month old baby to sleep unless she is in carrier. We basically rely very much in carrier to put baby to sleep. But I don't like the idea of using carrier always for fear of future spine problem later on when she grows up. Any other ideas on how to put new born baby to sleep? So far I tried putting her in bouncer, baby swing, lying on her back, sleeping on her tummy, all these didn't work. She didn't even feel sleepy.
