You're focusing on making mistakes instead of what is really important - you're creating something out of love for those you love. Do your best and know that its a process. I guarantee you that your children will love their quilts because you made them, and you'll be look back on this time and realize that it was a bonding experience with your babies. You'll also realize that quilting is exactly like life -- we learn a little bit more every day, that we're surrounded by good examples to follow and that we learn much more from our mistakes than our successes! Have fun and post pictures!
