DD sits just fine, if we put her there. But if she is on her back or belly, she will not sit up on her own. She'll whine until one of us sits her up. She has been crawling for almost two months, and rolled over early as well. My mom thinks it's weird that she won't sit up on her own, and now I'm starting to worry. Has anyone else experienced an early roller/crawler but late sitter-upper?
Re: Almost 8 month old not sitting up on her own?
I wouldn't let your mom get you worried. My MIL always had me worried at some milestone like when DD didn't "find" her hands or when she didn't roll over, or when she didn't hold a spoon or drink from a sippy cup. Eventually she learned how to do all those things. She just does it at her own pace.
DS didn't learn how to get into a sitting position until he crawled. However, he learned how to crawl differently than most kids--he started from a sitting position and leaned forward until he was on all fours. So, he had lots of practice leaning forward and pushing himself back up.
Can you try showing her how to do it by walking her backwards from a crawling position?
