Hi E.,
She seems like a very healthy baby, just on track for me.
For the crawling, some do crawl at 6 months (or before), some at 12 months and some never crawl at all. This is not a milestone. Some babies crawl for months before standing or walking. Other go from crawling to walking in a matter of weeks or even days!
Same for the babbling. Not many babies say mama or dada at 7 months. Some don't even approach it at 12 months and are all "normal"
Her weights is just on track according to my ped's chart.
No worries. She's just fine. Enjoy this blessing time. We are so eager to see them crawl and walk and then we missed the peaceful time when they couldn't escape or run to the danger :-)
