I had been trying to lose weight by running for about thirty minutes every day. But I've found that's it's not easy to stick with. Because after many day's of working out I found that i didn't lose any weight at all, which psyched me out of working out, i would bow out then ( < not sure what this means).I mean, I couldn't roll over any faster at that time.

If what you're trying to say is that the mother is with her baby in the mothers bed then you could just write "the mother is nursing the sleeping baby in her own bed"

"It's estimated at $200, it it shouldn't be $50 more or less" is an easy way of putting, your friend did a pretty good job at that sentence, I guess it's just a long way of putting it
