It is a terrible feeling to suspect that your child may not be developing the way they should - do NOT despair. Amanda was EXACTLY as you describe at one year - did not phonate words, made sounds more akin to the whines and mewlings, could/would not stand up without holding onto furniture or hands. She did not say her first word, or stand up and walk until damn near 14-15 months.
I had the same type of fears you did. Every child develops at a different rate, don't let the charts or experts cause you undue alarm - before long, you will be thinking wistfully of the time when they could not walk and talk, after the 12th time you turn around for 5 seconds and he disappears, only to be found trying to give the cat a bath in the toilet!

If you want to email me, please feel free - I would be more than happy to share stories, help, and support
