My 8-month old DD has always *hated* tummy time. When I say *hated*, I don't mean fussing a bit, but can be easily distracted by toys etc.
I always got down on my tummy with her, like they tell you to do, and tried every trick in the book to distract her. She didn't care! She would *sob* and *scream* like she was being murdered!
I practice Gentle Parenting so this was especially hard on me, and tummy time was few and far between for a while.

About a month ago I felt like I needed to step it up, and she now tolerates it, and has quit sobbing and screaming. She fusses a bit, but I have to work hard to entertain her in various ways to try and keep her there. I try to give her an hour of tummy time a day, with two 30-minute sessions.
She can roll from tummy to back, but has absolutely no interest in rolling from back to tummy.
I think it is because she simply prefers her back, and has no desire to roll back to the horrid tummy position!

Now to the issue with crawling - I am worried that she isn't going to crawl at all, and despite health professionals telling me this is a normal variation, I also keep reading (well, Googling) that non-crawlers end up having speech problems, A.D.D., and dyslexia, just to name a few scary things.
I have been in tears many times about this.

I know the issues have something to do with right-left brain development, which non-crawlers do not get. But surely there are other ways to develop the brain in this way??? Anyone know?

Also, if anyone has any positive stories about non-crawlers who are now school-aged children, and who do not have any problems whatsoever, please share! I have heard every scary story in the book and don't need to hear any more...
