When Did

When did your baby start sitting up alone? When did your baby start crawling? When did he/she say mama or dada? and when did he or she start walking? I'm worried my daughter might be falling behind she goes to PT to help her crawl, rolling, and sit up on her own and help with her head turning problem ( it got a lot better)

sitting up - 6-7 months
crawling - 9 months
Saying mama/dada - 6 months?
walking - she is 14 months and still barley walking, but she is getting there

my son is turning 7 months in a few days and he just started sitting a couple weeks ago and started crawling last week.

my daughter is 5 months and everyone said she should be crawling true or false ?

I'm coping this from my blog so sorry for the "formal" layout.

Quoting Lillie Montalvo:" my daughter is 5 months and everyone said she should be crawling true or false ?"

false

Quoting Lillie Montalvo:" When did your baby start sitting up alone? When did your baby start crawling? When did he/she say mama ... [snip!] ... she goes to PT to help her crawl, rolling, and sit up on her own and help with her head turning problem ( it got a lot better)"

My first son started sitting up at 5 months old, crawling at 9 months old, saying momma and dada at 6 months old, walking around furniture at 7 months old, and then actually walking by himself at 11 months old.

My son started sitting up a week and before 4 months old, but he did a lot of things early.
