My little one is 2 months old now. I like to sit her on the corner of my sofa as she will be supported by the 2 sides of the sofa (L shape corner). However I have friends who say doing that is not good as it will have problems with the development of baby's spine. Is it true? Can't find much info on Google so thought of asking here.

Sitting is a developmental milestone, so I wouldn't rush it. It isn't advisable to prop your child up in a seated position when she isn't ready for it yet as it may be detrimental to her spinal development. Her neck muscles are also not strong enough to support her head as of yet. Do try placing her in a bouncer or rocker meant for newborns. http://blog.intellidance.ca/blog/2-15-2011/c-s-how-nurture-your-babys-spine-development http://www.babycentre.co.uk/a6505/developmental-milestones-sitting
