Baby progress

Megan
My daugther is about 7 weeks. Shes my first and im not exactly sure where she should be with her progress. She can kinda hold her head up, but not for more than 30 to 45 seconds at a time. She can scoot her whole body about 3 inches over. And shes trying to crawl. But im not sure if she should already be holding her head up completely or not. Any tips or ideas?
